[0023] With reference to FIGS. 1-11, reference numeral 10 generally designates a cleaning apparatus that includes a suction source 12 in fluid communication with a suction inlet 14 for capturing debris materials. The cleaning apparatus 10 also includes a separation and collection assembly 16 in fluid communication with the suction inlet 14 and the suction source 12. The separation and collection assembly 16 is generally disposed along an airflow path 18 between the suction inlet 14 and the suction source 12. The separation and collection assembly 16 may include a recovery tank 20 defining a collection chamber 22 and a filter housing 24 disposed along the airflow path 18 between the collection chamber 22 and the suction source 12.

[0024] A filter shroud 26 has a proximal end 28 operably coupled with the filter housing 24 and a distal end 30. The filter shroud 26 includes a shroud wall 32 that extends into the collection chamber 22. Debris deflecting ribs or fins 34 extend outward from the shroud wall 32. Each deflecting fin 34 extends along at least a portion of a length of the filter shroud 26 between the proximal end 28 and toward the distal end 30. The suction source 12 is configured to generate a toroidal and/or cyclonic airflow within the separation and collection assembly 16 for separating the debris materials from working air. At least one of the filter shroud 26 and the deflecting fins 34 is configured to rotate about a central axis 36 of the separation and collection assembly 16, including the filter shroud 26, with the cyclonic airflow.

[0025] Referring to FIG. 1, the cleaning apparatus 10 generally includes a suction assembly 50 including the suction source 12 for generating the vacuum or suction effect at the suction inlet 14 to capture the debris material from the surface being cleaned. Based on the configuration and use of the cleaning apparatus 10, the surface being cleaned may be an underlying surface or another surface, which may be horizontal or vertical surfaces. The vacuum or suction effect generated by the suction source 12 is configured to draw air, which may be referred to as the working air, and the debris material into the cleaning apparatus 10 and direct the working air and debris materials along the airflow path 18. The air and debris materials are drawn into the separation and collection assembly 16, where the debris material is separated from the working air and collected in the recovery tank 20 for later disposal. The working air is directed through separation and collection assembly 16, through a filter assembly 52, through the suction assembly 50, and is exhausted from the cleaning apparatus 10 at an exhaust outlet 54. Each of the suction inlet 14 and the exhaust outlet 54 may be a single opening or multiple openings.

[0026] The cleaning apparatus 10 may include a cyclonic separation system 60 that can include at least the suction source 12, the suction inlet 14, and the separation and collection assembly 16. The cyclonic separation system 60 is configured to separate the debris materials from the working air using the rotational, toroidal, and/or cyclonic airflow within the recovery tank 20 where the debris materials are separated from the airflow by centrifugal force. In certain aspects, the separation and collection assembly 16 may provide for a single stage of separation (i.e., a single cyclonic separation stage) or more than one stage of cyclonic separation (i.e., multiple cyclonic stages). In the cyclonic system, the recovery tank 20 has a cylindrical or frusto-conical shape formed by an outer tank wall 62, which may assist generation or directing with the rotating airflow pattern. In this regard, the collection chamber 22 may also be referred to as a cyclonic chamber. An inlet conduit 64 is coupled with the outer tank wall 62 and in fluid communication with the collection chamber 22.

[0027] Airflow through the inlet conduit 64 is generally normal to the central axis 36 of components of the separation and collection assembly 16, including the filter shroud 26 and the recovery tank 20. With this configuration, the airflow generated by the suction source 12 may draw air and debris material into the collection chamber 22, forming the rotating, cyclonic airflow around the central components of the system 60, as further described herein. The cyclonic airflow is generally a high-speed, spinning airflow that causes the debris material to separate from the working air through the centrifugal force. As used herein, the terms debris material(s) may include dirt, soil, dust, hair, stains, lint, food, and other similar dry or semi-dry materials.

[0028] In more conventional arrangements, the cyclonic air pattern may carry long and/or soft debris material, such as hair into a dirty tank. The hair is spun with the cyclonic air pattern and typically wraps around a stationary central component, such as a shroud or cover component. The hair, being spun with the air, wraps and tangles around the outside of the cover component, which can reduce or block airflow out of the dirty tank, reduce the separation of the debris from the air, and reduce suction at an airflow inlet. Further, the wrapped and tangled debris or hair can result in increased maintenance and cleaning for a user or consumer.

[0029] Referring still to FIG. 1, the separation and collection assembly 16 described herein includes a rotating deflector 70 within the collection chamber 22. The rotating deflector 70 can have different configurations such as a deflector sleeve 72 (see FIGS. 7 and 8), a deflecting shroud 74 (see FIGS. 9 and 10), or a rotating shroud 26 (see FIG. 11) described herein, which may collectively be referred to as the rotating deflector 70. The rotating deflector 70 may be moved by the cyclonic airflow in the recovery tank 20. In this way, the suction source 12 causes the cyclonic airflow and, consequently, rotates the rotating deflector 70.

[0030] The rotating deflector 70 is configured to rotate about the central axis 36 of the separation and collection assembly 16, including central axis 36 for the filter shroud 26 and the recovery tank 20. The rotating deflector 70 may deflect the debris material away from an outer surface 78 of the filter shroud 26, assisting with separating the debris materials from the working air. In certain aspects, this debris includes long/soft debris, such as hair, and the rotating deflector 70 may deflect the long, soft debris material away from the filter shroud 26 to reduce or prevent the long, soft debris material from wrapping or tangling around the filter shroud 26. This rotating deflector 70 may, therefore, improve airflow through the filter shroud 26, increase the separation of the debris material from the working air, and increase the suction at the suction inlet 14. Further, the rotating deflector 70 may decrease maintenance and cleaning for the consumer. As described further herein, the rotating deflector 70 may be the deflector sleeve 72, which can be a separate component with the deflecting fins 34 that extends and rotates around the filter shroud 26 (see FIGS. 7 and 8), the deflecting shroud 74, which includes the filter shroud 26 and the deflecting fins 34 as a single integrated component (see FIGS. 9 and 10), or the rotating filter shroud 26 with the deflecting fins 34 omitted (see FIG. 11).

[0031] Referring still to FIG. 1, as well as FIG. 2, the cleaning apparatus 10 may have a variety of configurations. For example, the cleaning apparatus 10 may be a vacuum cleaner. The vacuum cleaner may be usable in an upright mode of operation where the vacuum cleaner can be maneuvered along the underlying surface or a floor surface. In the illustrated configuration of FIG. 2, the cleaning apparatus 10 is an upright vacuum cleaner that is often referred to as a stick vacuum. The cleaning apparatus 10 may also be a portable unit or have a removable portable unit, such as a carrying or hand module 90 included in FIG. 2. In such examples, the cleaning apparatus 10 or a portion of the cleaning apparatus 10 may be hand-carried by the user. The portable unit may be smaller and lighter to allow the user to carry the portable cleaning apparatus 10. In certain aspects, the cleaning apparatus 10 may be used in the upright cleaning mode, as well as in one or more handheld, portable modes.

[0032] Referring still to FIG. 2, as well as FIGS. 3-5, the cleaning apparatus 10 generally includes a foot or base 92 for engaging the underlying surface and an elongated wand 94 extending from the base 92. The elongated wand 94 may be operably coupled with the base 92 to operate as an upright support for the cleaning apparatus 10 and may also be separated from the base 92. It is contemplated that the cleaning apparatus 10 may have an upright housing in lieu of the removable elongated wand 94. The cleaning apparatus 10 can also include the handheld or hand module 90 coupled to the elongated wand 94. In this way, the elongated wand 94 can extend between and couple the base 92 and the hand module 90 and can also be removable from both. Alternatively, the hand module 90 may be disposed proximate to the base 92. The hand module 90 may include a handle 96 for maneuvering the cleaning apparatus 10. In non-limiting examples, the hand module 90 may support or include the suction assembly 50 and the separation and collection assembly 16.

[0033] Referring again to FIGS. 2-4, the cleaning apparatus 10 may include or be associated with a storage bracket 100, which may hold and store the cleaning apparatus 10 in a stowed state. The storage bracket 100 may be configured to selectively engage a wall surface for storing the cleaning apparatus 10. The cleaning apparatus 10 may be disengaged from the storage bracket 100 for the cleaning process. Additionally, the storage bracket 100 may be configured to hold and store various accessories and tools 102 that can be utilized with the cleaning apparatus 10.

[0034] In certain aspects, the cleaning apparatus 10 may include a power source 104, such as a battery or battery pack. The cleaning apparatus 10 may also include a power cord for engaging a power outlet, such as a household electrical outlet. The power source 104 may be configured to power various electrical components in the cleaning apparatus 10, such as the suction source 12. A power switch 106 may be arranged between the power source 104 and the electrical components. The power switch 106 can be selectively closed by the user to activate the electrical components.

[0035] Referring still to FIGS. 3-5, an exemplary cleaning apparatus 10 is illustrated. The cleaning apparatus 10 includes at least one suction inlet 14 for capturing debris materials from the surface being cleaned. Depending on the configuration of the cleaning apparatus 10, the cleaning apparatus 10 may have multiple suction inlets 14 that can be used for different cleaning processes. Each suction inlet 14 may be in fluid communication with the suction source 12 and may be disposed along the airflow path 18. It is contemplated that different airflow paths 18 may be formed with the different suction inlets 14 without departing from the teachings herein.

[0036] The cleaning apparatus 10 includes the base 92 for engaging the underlying surface and the elongated wand 94, which can be removably coupled with the base 92. The base 92 includes a base housing 110 and wheels 112 operably coupled to the base housing 110. The base 92 is adapted to be moved relative to the underlying surface via the wheels 112. In various aspects, the base 92 defines, includes, or is in fluid communication with at least one suction inlet 14, which may be referred to as a base suction nozzle 114. Movement of the base 92 is configured to move the base suction nozzle 114 relative to the surface being cleaned.

[0037] Referring to FIGS. 3 and 4, the base 92 may also include an agitator 116 operably coupled to the base housing 110. The agitator 116 may be positioned proximate or adjacent to the base suction nozzle 114 and is configured to agitate the surface being cleaned to disrupt the debris materials. Disruption of the debris materials on the surface being cleaned may assist with capturing the debris materials with the suction effect at the base suction nozzle 114. The agitator 116 may be configured as at least one brushroll, at least one horizontally rotating brushroll, at least one vertically rotating brushroll, at least one stationary brushroll, etc. The agitator 116 may be operably coupled with an agitator drive system 118, which may include a motor, gears, etc. for rotating or otherwise moving the agitator 116.

[0038] The base 92 is operably coupled with a conduit 126 that is in fluid communication with the base suction nozzle 114. In the illustrated configuration, an inlet of the conduit 126 is disposed proximate to the agitator 116 and an outlet of the conduit 126 is disposed proximate to the elongated wand 94. The conduit 126 is configured to provide fluid communication between the base suction nozzle 114 and the elongated wand 94. A connector 128 may be coupled or included in the base 92. The connector 128 may define a receiving passage 130 for an inlet end 132 of the elongated wand 94, as well as the outlet of the conduit 126. The receiving passage 130 may fluidly couple the conduit 126 and the elongated wand 94.

[0039] The conduit 126 extends between the base housing 110 and the connector 128 and may be flexible for allowing movement of the elongated wand 94 relative to the base 92. The conduit 126 may extend generally horizontally from the base housing 110 and then curve to extend generally vertically toward the elongated wand 94. The conduit 126 is configured to guide the debris material and working air from the base 92 and toward the elongated wand 94 along the airflow path 18. The connector 128 may be coupled with a coupling joint 134 to operably couple the base 92 with the elongated wand 94. The coupling joint 134 may be disposed proximate to the conduit 126, and, in certain aspects, the conduit 126 can extend through the coupling joint 134. The coupling joint 134 can be a pivoting, single-axis joint or may be a rotational, multi-axis joint.

[0040] Referring still to FIGS. 3-5, as illustrated, the elongated wand 94 forms a portion of the airflow path 18 between the base 92 and the hand module 90. The connector 128 may include a latch 136 for engaging and disengaging the inlet end 132 of the elongated wand 94 with the connector 128 and, consequently, the base 92. The inlet end 132 of the elongated wand 94 may be inserted into the receiving passage 130 and configured to lock to the connector 128 via the latch 136. The elongated wand 94 may also be removed from the receiving passage 130 and used separately from the base 92, alone or with the accessory or tool 102.

[0041] When the elongated wand 94 is removed from the receiving passage 130, the suction source 12 is no longer in fluid communication with the base 92 due to disruption in the airflow path 18. The suction source 12 remains in fluid communication with the elongated wand 94, and the inlet end 132 of the elongated wand 94 can form one of the suction inlets 14, which may be referred to as a wand suction nozzle. The wand suction nozzle can be manually maneuvered relative to the cleaning apparatus 10 and along the surface being cleaned. This configuration may be advantageous for applying the suction effect to small areas or crevices, as well as for vertical surfaces.

[0042] The inlet end 132 may be coupled with the accessory or tool 102. The tool 102 is configured to utilize features and functions of the cleaning apparatus 10, such as the suction assembly 50. In such examples, the suction assembly 50 can be used to generate the suction effect at a tool suction nozzle (e.g., one of the suction inlets 14). The tool 102 can be manually maneuvered by the user relative to the surface being cleaned. The tool 102 may provide different or additional functions and features to the cleaning apparatus 10 for different cleaning processes. For example, the tool may be a dusting brush, a crevice tool, a pet hair tool, or any other tool that can utilize the suction or vacuum effect. The tool 102 can maximize the user experience by allowing the user to utilize the tool 102 separately from the base 92 for collecting debris material.

[0043] Additionally, in examples where the cleaning apparatus 10 includes the detachable hand module 90, an outlet end 138 of the elongated wand 94 may be removably coupled from the hand module 90 for using the hand module 90 separate from the elongated wand 94 and/or the base 92. The hand module 90 may define or include a receiver 140, which can receive the outlet end 138 of the elongated wand 94 and/or an end of the tool 102. A latch 142 may be included on the hand module 90 for securing the elongated wand 94 or the tool to the hand module 90. It is contemplated that the receiver 140, which forms a portion of the airflow path 18, can also form an additional suction inlet 14 for using the hand module 90 without the elongated wand 94 or the tool 102.

[0044] Referring now to FIGS. 5 and 6, the hand module 90 may include the handle 96 for the user to grasp and maneuver the cleaning apparatus 10 relative to the surface being cleaned. The handle 96 may include a user interface 150 for activating one or more components of the cleaning apparatus 10. The handle 96 may be included in or operably coupled with a frame or body 152. The body 152 may provide support or house various components of the cleaning apparatus 10. In non-limiting examples, the battery 104 may be at least partially housed within the body 152.

[0045] The suction assembly 50 may be at least partially disposed within the body 152. The suction assembly 50 is in fluid communication with the suction inlet 14 for generating the working airflow along the airflow path 18. The suction assembly 50 generally includes a motor/fan cover or housing 154, and the suction source 12 is disposed at least partially within the motor/fan housing 154. The motor/fan housing 154 may be a single integrated component or formed of several components coupled together. The suction source 12 may be or include a motorized fan assembly or vacuum motor. In various aspects, the suction source 12 may include an impeller assembly 156 operably coupled with a motor 158, which drives the impeller assembly 156. The suction source 12 may have any configuration that generates the vacuum/suction effect through the cleaning apparatus 10.

[0046] The cleaning apparatus 10 generally includes or defines the exhaust outlet 54 proximate to the suction assembly 50. For example, the exhaust outlet 54 may be defined by the body 152 proximate to the suction assembly 50, such as on an opposing side of the body 152 compared to the recovery tank 20. The suction source 12 is configured to direct the air along the airflow path 18 and exhaust or vent the air from the cleaning apparatus 10 via the exhaust outlet 54.

[0047] An insert 160 may couple the motor/fan housing 154 with the filter housing 24 and the recovery tank 20. The insert 160 defines or includes motor inlets 162, through which the suction source 12 is configured to draw air along the airflow path 18 between the recovery tank 20 and the suction assembly 50. The insert 160 may be coupled with the filter housing 24, which defines a filter chamber 170. The filter chamber 170 may house a filter 172, which may be referred to as a tank filter or pre-motor filter.

[0048] Referring still to FIGS. 5 and 6, the body 152 may include an engagement hook 176 for supporting the recovery tank 20. The body 152 and the recovery tank 20 may include mating components of a latch assembly 178 for coupling the recovery tank 20 to the body 152. The recovery tank 20 may be operably coupled with the filter housing 24 to enclose the collection chamber 22 and form a portion of the airflow path 18. The recovery tank 20 includes the inlet conduit 64, which is coupled with an outlet conduit 180 of the body 152 to provide fluid communication between the suction inlet 14 and the recovery tank 20. The airflow into the recovery tank 20 is generally normal or perpendicular to a longitudinal extent of the recovery tank 20 and the central axis 36 for providing the cyclonic or toroidal airflow within the recovery tank 20.

[0049] The recovery tank 20 may be included in the separation and collection assembly 16. The recovery tank 20 includes or defines the collection chamber 22 for collecting debris materials. The recovery tank 20 includes the outer tank wall 62, which has the cylindrical or frusto-conical shape for driving the rotational airflow. The recovery tank 20 also includes a bottom wall 186, enclosing a lower portion or bottom of the collection chamber 22 for collecting or recovering debris materials for later disposal. In various aspects, the bottom wall 186 may be integrally formed with the outer tank wall 62. Alternatively, the bottom wall 186 may include or form a door that can be selectively opened for releasing the contents of the collection chamber 22. The recovery tank 20 may include an open-ended, hollow or tubular protrusion 188 extending from the bottom wall 186. The tubular protrusion 188 may assist in forming the toroidal airflow and may also provide a space for collecting debris material as described herein.

[0050] The filter shroud 26 is centrally located within the recovery tank 20. The central axis 36 of the filter shroud 26 is generally the same as the central axis 36 for the recovery tank 20, the filter housing 24, and, in certain aspects, the suction assembly 50. The central axis 36 of the filter shroud 26 and the recovery tank 20 may be the same or coaxial, with the filter shroud 26 disposed within the collection chamber 22. The filter shroud 26 may be operably coupled with the filter housing 24 to position the filter shroud 26 toward a top or upper portion of the collection chamber 22 proximate to the inlet conduit 64. The filter shroud 26 includes the shroud wall 32 having the proximal end 28 disposed proximate to the inlet conduit 64 and the distal end 30 disposed proximate to the tubular protrusion 188. The filter shroud 26 serves to protect the filter 172 from larger debris material.

[0051] The filter shroud 26 may define a plurality of apertures 194, which may be sized to allow the airflow and/or small or fine debris material to flow therethrough while reducing or preventing larger debris material from flowing therethrough. The apertures 194 may be arranged over a substantial portion or the entire outer surface 78 of the shroud wall 32 (see FIG. 7) or may be formed on a section or band around the shroud wall 32. The filter shroud 26 is generally a hollow, tubular structure, allowing airflow through the shroud wall 32 and the hollow interior. The distal end 30 of the filter shroud 26 may at least partially enclose the hollow interior of the filter shroud 26. The distal end 30 may define a central opening 196 for small or fine debris material to be collected in the tubular protrusion 188.

[0052] The filter shroud 26 may include or be coupled with an end feature 198, which may be a plate or skirt that assists with the separation process. Additionally or alternatively, the end feature 198 may have an increased width compared to a width defined by the shroud wall 32. The increased width may assist in retaining the deflector sleeve 72 (FIGS. 7 and 8) on the filter shroud 26 in configurations where the rotating deflector 70 is a separate component.

[0053] The filter shroud 26 may separate an outer chamber portion 202 of the collection chamber 22 from an inner chamber portion 204 of the collection chamber 22. The inner chamber portion 204 may be downstream of the outer chamber portion 202 along the airflow path 18. A separator body 210 may be disposed in the filter shroud 26. The separator body 210 may include a tubular section at an upper end (proximate to the filter housing 24) and a tapering, frusto-conical section at a lower end. The separator body 210 extends through the hollow interior of the filter shroud 26 and at least partially through the central opening 196. The separator body 210 includes or defines at least one inlet opening and at least one outlet opening 212, which is illustrated as two opposing openings 212 at the distal end thereof. The distal end 30 may operate as a vortex stabilizer.

[0054] Referring still to FIGS. 5 and 6, the distal end of the separator body 210 extends into the tubular protrusion 188 of the recovery tank 20. The interior of the filter shroud 26 and the interior of the separator body 210 are in fluid communication with the interior of the tubular protrusion 188 to allow small or fine debris to fall through the openings and be collected in a collection space of the tubular protrusion 188. In certain aspects, as described further herein, the filter shroud 26 may be configured to rotate about the separator body 210 and the tubular protrusion 188. The suction source 12 is configured to draw air through the filter shroud 26, into the interior of the separator body 210, and toward the filter 172.

[0055] The filter assembly 52 can include the filter housing 24, which may include a filter frame 216. The filter frame 216 can extend into the interior of the separator body 210. For example, the filter frame 216 may include a hollow, tubular conduit 218 that may operate as a vortex finder. A lower portion of the hollow tubular conduit 218 may be open to allow the air to be drawn through the filter 172 and toward the suction source 12.

[0056] At least the filter shroud 26, the filter housing 24 including the filter frame 216, and the filter 172 may form the filter assembly 52. The filter assembly 52 may also include the separator body 210. The filter assembly 52 and the tubular protrusion 188 of the recovery tank 20 can be aligned coaxially with one another on the central axis 36. This positions the components at a center of the collection chamber 22, extending from a top to a bottom of the collection chamber 22, which can assist with the forming or generating the toroidal or cyclonic airflow around these central components.

[0057] Referring still to FIGS. 5 and 6, the cyclonic separation system 60 can provide a single-stage cyclonic separation process or may provide a two-stage cyclonic separation process. In the two-stage process, a first stage is defined in the outer chamber portion 202 of the collection chamber 22 for separating larger debris materials from the working airflow, and a second stage is defined by the inner chamber portion 204 for subsequently separating the smaller debris material from the airflow. Generally, one or both of the cyclonic stages may be centered on the central axis 36. The first and second stages may be concentric with the second stage positioned within the first stage and both centered on the central axis 36. It is contemplated that additional separation stages or a single separation stage may also be utilized without departing from the teachings herein.

[0058] With two separation stages, the first cyclonic separation stage can be defined in the outer chamber portion 202. The air and debris materials are drawn into the collection chamber 22 and spun or rotated around the filter shroud 26. The suction source 12 is configured to generate a high-velocity airflow, which causes the larger debris to separate from the airflow and be collected at a bottom of the outer chamber portion 202. The airflow, along with smaller or fine debris materials, is directed by the suction source 12 through the apertures 194 of the filter shroud 26 for the second cyclonic separate stage.

[0059] The air is configured to rotate or spin around and within the separator body 210. The high-velocity rotational airflow within the inner chamber portion 204 causes the smaller debris material to separate from the airflow. The smaller debris material is configured to fall through the openings 212 of the separator body 210 to be collected in the collection space in the tubular protrusion 188 (e.g., the bottom of the inner chamber portion 204). The inner collection space is generally located below the separator body 210 to collect the debris material using gravitational forces.

[0060] The airflow is then directed through the tubular conduit 218 of the filter frame 216 and into the filter chamber 170. The filter 172 may be arranged downstream of the two stages of cyclonic filtration. The working air may pass through the filter 172 before reaching the suction source 12. The filter 172 can be removably received in the filter chamber 170. The filter 172 may be any porous, non-porous, folded, pleated, etc. material or media for further filtering the airflow before the air is directed around or through the suction source 12. The air can be directed through the motor/fan housing 154 and the suction source 12. An outlet conduit may be formed by the motor/fan housing 154 for directing the air toward and through the exhaust outlet 54.

[0061] Referring to FIGS. 5 and 6, in cyclonic-based cleaning apparatuses 10, the separation of debris material from the working air may be achieved through centrifugal force. The debris-carrying working air may be rotated or spun at high speeds by the suction effect generated by the suction source 12 and the configuration of the separation and collection assembly 16, including the recovery tank 20 and the filter shroud 26. This spinning or rotational airflow may cause heavier particles in the debris material to be separated into the collection chamber 22 while the working air passes through the filter 172 and is exhausted out of the cleaning apparatus 10. A common problem in more conventional cyclonic systems is a tendency for long and soft debris, such as hair, to wrap around the shroud component, which can lead to blockages, reduced suction power for the blower, and increased maintenance.

[0062] Referring to FIGS. 6-11, the system 60 disclosed herein includes the rotating deflector 70 for deflecting debris material away from the filter shroud 26, including long/soft debris. The rotating deflector 70 may also be referred to as an anti-tangle feature. The rotating deflector 70 may reduce or prevent debris material from wrapping or tangling around the filter shroud 26, which may improve the efficiency of the cleaning apparatus 10 by maximizing the airflow through the separation and collection assembly 16 and maximizing the suction effect.

[0063] The rotating deflector 70 includes the deflecting fins 34 that extend or protrude radially outward from shroud wall 32 of the filter shroud 26. The deflecting fins 34 may extend a distance from the outer surface 78 that allows free rotation of the rotating deflector 70 within the collection chamber 22 (e.g., without significant impingement from the outer tank wall 62) while reducing soft, long debris from tangling around the filter shroud 26. In circumstances where some long, soft debris may be caught around the rotating deflector 70, the debris may be more conveniently removed due to the spacing between the debris material and the outer surface 78 of the shroud wall 32 by the deflecting fins 34.

[0064] The rotating deflector 70 is configured to rotate with the airflow in the collection chamber 22. In this way, the cyclonic airflow causes and drives the rotation of the rotating deflector 70. The motion of the cyclonic airflow causes the motion of the rotating deflector 70 to reduce or prevent entanglement of the soft debris material. The rotating deflector 70 may be configured to rotate freely or with minimal resistance, following the motion of the airflow in the collection chamber 22. Additionally, the separation system 60 may include a wiping feature or a wiper 226 for wiping, scraping, or otherwise cleaning the outer surface 78 of the filter shroud 26. The wiping feature may be provided by the rotating deflector 70, or the wiper 226 may be a separate component.

[0065] Referring to FIGS. 7 and 8, the rotating deflector 70 may be a separate component, such as the deflector sleeve 72 disposed about the filter shroud 26. The deflector sleeve 72 is a generally tubular and hollow component or sleeve fitted about the filter shroud 26. The deflector sleeve 72 may include a connecting frame 230 and the deflecting fins 34 extending from the connecting frame 230. The connecting frame 230 generally encircles the filter shroud 26, extending adjacent to the outer surface 78 of the filter shroud 26. The connecting frame 230 generally includes a proximal, first end segment 232 disposed proximate to the proximal end 28 of the filter shroud 26 and a distal, second end segment 234 spaced from the first end segment 232 and proximate to the distal end 30 of the filter shroud 26. Connecting segments 236 are arranged at intervals and extend between the first and second end segments 232, 234. Openings are defined between adjacent connecting segments 236 to allow air to flow through the deflector sleeve 72 and the shroud wall 32.

[0066] The connecting frame 230 may also include additional intermediate segments disposed between and extending generally parallel to the end segments 232, 234. In this way, the connecting frame 230 may have multiple segments (including end segments 232, 234) extending around the circumference of the filter shroud 26 and multiple connecting segments 236 extending between the proximal end 28 and the distal end 30 of the filter shroud 26. The connecting frame 230 may include any practicable number of circumferential segments (including end segments 232, 234) and connecting segments 236.

[0067] The connecting segments 236 generally extend parallel to one another. The connecting segments 236 may be spaced at equidistant or irregular intervals. The deflector sleeve 72 includes the deflecting fins 34 extending along the connecting segments 236. The deflecting fins 34 may be coupled with or integrally formed with the connecting frame 230. The deflecting fins 34 extend outwardly from connecting segments 236 and away from the outer surface 78 of the filter shroud 26.

[0068] In the example illustrated in FIG. 7, the connecting segments 236 extend at an angle between the end segments 232, 234 such that a junction between each connecting segment 236 and the first end segment 232 is offset from a respective junction between the connecting segments 236 and the second end segment 234. The deflecting fins 34 extend between the end segments 232, 234, extending a substantial or entire length of the connecting segments 236. The deflecting fins 34 may not extend over the end segments 232, 234. The deflecting fins 34 may have at least one arc or curve for extending at the angle around a curvature of the filter shroud 26 with the connecting segments 236. The angled orientation may assist with rotating the deflector sleeve 72.

[0069] In the example illustrated in FIG. 8, the connecting segments 236 extend normal to the end segments 232, 234 and parallel with the central axis 36. The deflecting fins 34 extend from the second end segment 234 and toward the first end segment 232. The deflecting fins 34 may be spaced from the first end segment 232 (e.g., offset from a centerline between the end segments 232, 234), which may provide a margin for movement in a direction parallel with the central axis 36 (e.g., up-and-down movement) during rotation without movement of the deflecting fins 34 being significantly impeded by the filter housing 24. The deflecting fins 34 may extend over the second end segment 234 to an end of the frame 230 and may extend toward the first end segment 232. In examples where the apertures 194 are arranged in a band, the deflecting fins 34 may extend past the band of apertures 194 in the filter shroud 26.

[0070] The deflecting fins 34 may be longer or shorter or at other angles/arrangements without departing from the teachings herein. The deflecting fins 34 in FIGS. 7 and 8 extend a substantially similar distance from the connecting segments 236 along a length of the deflecting fins 34. In this way, the deflecting fins 34 may form a substantially quadrilateral shape. The deflecting fins 34 for the defector sleeve 72 illustrated in FIG. 7 are substantially similar to one another, and the deflecting fins 34 for the defector sleeve 72 illustrated in FIG. 8 are substantially similar to one another. However, different configurations of the deflecting fins 34 may be included in a single deflector sleeve 72.

[0071] Further, the relationship between various components may differ depending on the size of the filter shroud 26 and/or the overall configuration of the cleaning apparatus 10. For example, the spacing between the connecting segments 236 and the filter shroud 26, the end segments 234 and the filter shroud 26, the end segments 234 and the end feature 198, between the end segments 234 and the proximal end 28, and/or the connecting segments 236 and the outer tank wall 62 of the recovery tank 20 may each be optimized to maximize the efficiency in rotating the rotating deflector 70. Similar spacing may be considered for the wiper 226 that is integral or affixed to the connecting frame 230. For example, too large of a gap/distance between the connecting segments 236 and/or wipers 226 and the filter shroud 26 may reduce the effectiveness of the wiping function/wiper 226 to wipe the shroud 26 clean as it rotates. Further, too large gap/distance between the end segments 234 and the filter shroud 26 can cause the sleeve to at least partially disengage or rotate off the shroud 26 during usage. The spacing of the components may assist in maximizing rotation of the rotating deflector 70 and wiping of the filter shroud 26 while minimizing impingement on the operation of the system 60.

[0072] The cyclonic airflow is configured to push against or catch the deflecting fins 34 and cause the deflector sleeve 72 to rotate about the central axis 36 and around the filter shroud 26. In this way, when the suction source 12 is activated and generating the airflow, the deflector sleeve 72 is also configured to rotate. Generally, the deflector sleeve 72 may freely move about the filter shroud 26 being retained between the filter housing 24 and the end feature 198 based on the size of these components, rather than through a direct mechanical coupling with another component. However, it is contemplated that deflector sleeve 72 may be coupled with a bearing or similar feature and/or the filter housing 24 for assisting with the rotation of the deflector sleeve 72 (similar to the configuration described with respect to FIGS. 9 and 10).

[0073] The deflector sleeve 72 is configured to rotate separately from the filter shroud 26, which may be fixed relative to the filter housing 24. Accordingly, the filter shroud 26 may remain generally stationary within the collection chamber 22 while the deflector sleeve 72 rotates about the stationary shroud 26. However, the filter shroud 26 may also rotate without departing from the teachings herein (see FIGS. 9-11).

[0074] The deflector sleeve 72 with the connecting frame 230 may also form or provide the wiper function (e.g., the deflector sleeve 72 may also be the wiper 226). During rotation, the connecting segments 236 may rotate past a circumference of the shroud wall 32 from the proximal end 28 to the distal end 30 when completing a full rotation about the central axis 36. Accordingly, the connecting frame 230 and the integrated deflecting fins 34 can form both the deflector sleeve 72 for deflecting long, soft debris materials and the wiper 226 for cleaning the outer surface 78 of the filter shroud 26.

[0075] The spacing between the connecting frame 230 and the shroud wall 32 may assist with wiping the surface of the filter shroud 26. This spacing between the deflector sleeve 72 and the filter shroud 26 may be less than one millimeter to provide sufficient spacing for rotation of the deflector sleeve 72 and sufficient closeness for the deflector sleeve 72 to wipe or brush the outer surface 78 of the filter shroud 26. The rotating deflector sleeve 72 may be configured to scrape, wipe, brush, or otherwise clean fine debris material, such as dust, from the outer surface 78 of the filter shroud 26 by rotating around the filter shroud 26. Cleaning the dust and other fine debris material from the outer surface 78 may increase airflow through the apertures 194 by reducing blockages caused by collecting dust.

[0076] In certain aspects, the wiper 226 may be integral or coupled with the connecting frame 230, such as the example illustrated in FIG. 8. The wiper 226 may be a separate feature built into or affixed to the connecting frame 230. For example, at least one of the connecting segments 236 may include the wiper 226. The wiper 226 may include multiple sections that extend along respective connecting segments 236. In such examples, the wiper(s) 226 may extend in an opposing direction from the connecting segments 236 compared to the fins 34. In other words, the fins 34 extend outward from an outer surface of the connecting segments 236 and away from the filter shroud 26, while the wipers 226 extend inward from an opposing inner surface of the connecting segments 236 and toward/to the filter shroud 26.

[0077] In such examples, the wipers 226 may have different properties compared to the connecting frame 230. The connecting frame 230 may be more rigid to be rotated by the cyclonic air, and the wipers 226 extending from the connecting segments 323 may be elastically deformable to engage the outer surface 78 of the filter shroud 26 to wipe the outer surface 78 without substantially affecting the rotation of the deflector sleeve 72. The wipers 226 may be elastomeric strips, bristles, bristly strips, elastomeric projections, etc.

[0078] Additionally, the wiper 226 may extend at different distances from the connecting segments 236 based on the spacing between the connecting segments 236 and the outer surface 78. For example, if the proximal end segment 230 is farther away from the outer surface 78 than the distal end segment 232, the wiper proximate the proximal end segment 230 may extend a greater distance compared to the wiper 226 proximate the distal end segments 232 to provide consistent/even wiping along the length of the filter shroud 26. The wiper 226 may extend the full length of the connecting segments 236 or a portion of the length of the connecting segments 226. Further, the wiper 226 may be a continuous feature or multiple features arranged at intervals (e.g., along the length of the connecting segments 236). In general, the wiper 262 may be affixed to at least one of the connecting segments 236 with the wiper 226 extending toward the outer surface 78 of the filter shroud 26 for engagement therewith to reduce fine debris on the outer surface 78 as the deflector sleeve 72 rotates.

[0079] Referring to FIGS. 9 and 10, the rotating deflector 70 may be the deflecting shroud 74, which includes the filter shroud 26 and the deflecting fins 34 formed as a single, integrated component. The deflecting fins 34 are coupled directly to or integrally formed with the outer surface 78 of the shroud wall 32. In such examples, the separation and collection assembly 16 may include a bearing 240 operably coupled between the filter housing 24 and the deflecting shroud 74. In certain aspects, the bearing 240 may be coupled with the filter frame 216, such as the tubular conduit 218, or elsewhere on the filter assembly 52. The deflecting shroud 74 is coupled with the bearing 240, allowing the deflecting shroud 74 to rotate about the central axis 36 and relative to the filter housing 24. The bearing 240 allows the rotation of the deflecting shroud 74 and reduces friction in the rotational movement. The bearing 240 may be incorporated into the system 60 to allow smoother rotation of the deflecting shroud 74. The bearing 240 may be a ball bearing, a low friction bearing, or other similar features and may be configured to withstand the environment within the cleaning apparatus 10 (e.g., high suction, moving debris, etc.).

[0080] In the illustrated configuration, the deflecting fins 34 are arranged closer to the proximal end 28 of the filter shroud 26 compared to the distal end 30. The deflecting fins 34 may extend along the portion of the length of the shroud wall 32, which may or may not extend beyond a centerline (normal to the central axis 36) of the filter shroud 26. The deflecting fins 34 may have a triangular or wedge shape, narrowing/tapering as the fins 34 extend toward the distal end 30. The smaller deflecting fins 34 may maximize airflow through the apertures 194 while deflecting the soft, debris material away from the filter shroud 26. The deflecting fins 34 are illustrated as being arranged parallel to the central axis 36 but may also be angled without departing from the teachings herein. Further, a second set of deflecting fins 34 may be arranged proximate to the distal end 30, which may be a mirror image or identical arrangement to the upper deflecting fins 34. Other configurations of the deflecting fins 34, such as those illustrated in FIGS. 7 and 8, may also be used with the integrated deflecting shroud 74. The cyclonic air may catch or push against the deflecting fins 34 and/or the shroud wall 32, causing the filter shroud 26 to rotate based on the engagement with the bearing 240.

[0081] The rotating shroud 26 with the deflecting fins 34 (i.e., the deflecting shroud 74) may deflect debris from the filter shroud 26 for collection in the collection chamber 22. Included in the deflected debris can be the long, soft debris such as hair, and the moving/rotating components can reduce or prevent the long debris material from wrapping or tangling around the filter shroud 26. The rotation of the filter shroud 26 may assist with removing fine debris material, such as dust, from the outer surface 78. However, the separate deflector of FIGS. 7 and 8 may have a greater impact in brushing the dust from the filter shroud 26.

[0082] In certain aspects, as illustrated in FIG. 11, the rotating deflector 70 may be the rotating shroud 26 with the deflecting fins 34 omitted. In such examples, the continuous rotational movement of the shroud 26 with the airflow can deflect the debris material away from the shroud wall 32. Further, the rotational movement may also reduce the long, soft debris from wrapping around the shroud 26.

[0083] Referring to FIGS. 9-11, to increase the dust and fine debris removal from the outer surface 78, the separation and collection assembly 16 may include the wiper 226. The wiper 226 may be a separate component utilized with the rotating shroud 26. The rotating shroud 26 may include the deflecting fins 34, as illustrated in FIGS. 9 and 10, or the deflecting fins 34 may be omitted, as illustrated in FIG. 11. The configuration of the wiper 226 may depend on the inclusion and configuration of the deflecting fins 34 to reduce or prevent the wiper 226 from substantially impinging the rotation of the rotating shroud 26. It is also contemplated that the separate wiper 226 may be used with the deflector sleeve 72, which can also operate as the wiper 226 to provide two wiping features.

[0084] The separate wiper 226 includes an outer frame 250, which may be disposed adjacent to an inner surface 252 of the outer tank wall 62. The outer frame 250 may also be coupled with or integrally formed with the outer tank wall 62. The outer frame 250 may be a solid component, such as a ring, or connected features similar to the connecting frame 230 (see FIGS. 7 and 8). The wiper 226 may generally be a stationary component that engages the rotating filter shroud 26. However, it is contemplated that the wiper 226 may rotate around the stationary filter shroud 26 or the rotating deflector 70 (including the rotating shroud 26 without the fins 34) without departing from the teachings herein. An additional bearing 240 or another similar structure may be used for the rotating wiper 226 when the wiper 226 is separate from the rotating deflector 70.

[0085] Engagement features 254 may be coupled to and extend from the outer frame 250. The engagement features 254 may extend toward the central axis 36. The engagement features 254 may extend in columns, patterns, etc., or over the entire outer frame 250. The engagement features 254 may be arranged in groupings around the filter shroud 26 and/or encircle the filter shroud 26 for dusting a portion of or the entire outer surface 78. The engagement features 254 may be arranged along the length of the filter shroud 26 for engaging the outer surface 78 from proximate to the proximal end 28 to proximate to the distal end 30. The engagement features 254 may be elastically deformable for engaging the filter shroud 26. The engagement features 254 may be spaced from the filter shroud 26, similar to the distance between the outer tank wall 62 and the connecting frame 230 (see FIGS. 7 and 8) and/or engage the outer surface 78 directly. The engagement features 254 may include bristles, squeegee feature(s), solid components, brushes, etc. to brush the dust off the outer surface 78. The wiper 226 is configured to scrape, wipe, brush, or remove the dust and fine debris from the outer surface 78.

[0086] Referring to FIGS. 1-11, in operation, the user can activate the cleaning apparatus 10 using the user interface 150, which can activate the suction source 12. The user can maneuver the suction inlet 14 along the surface to be cleaned to capture air and debris material with the vacuum effect. The vacuum effect generates the airflow through the cleaning apparatus 10, including the cyclonic airflow in the collection chamber 22. The cyclonic airflow in the collection chamber 22 causes rotation of the rotating deflector 70, such as deflector sleeve 72 with the connecting frame 230 and the deflecting fins 34, the deflecting shroud 74 with the filter shroud 26 with the integrated deflecting fins 34, or the rotating shroud 26.

[0087] The debris materials are configured to be directed into the collection chamber 22, where the high speed of the rotating airflow causes the larger debris material to be separated from the airflow due to the centrifugal force to be collected in the outer chamber portion 202. The rotating deflector 70 in the collection chamber 22 follows the motion of the airflow in the collection chamber 22, which may reduce or prevent long and soft debris from wrapping around the shroud 26. This may be due to the continuous motion of the rotating deflector 70 and/or the configuration of the deflecting fins 34. The air along with finer debris particles may pass through the apertures 194 in the filter shroud 26. Additionally, the deflector sleeve 72 with the connecting frame 230 or the separate wiper 226 may continuously scrape or brush debris material, such as dust, off the outer surface 78 of the filter shroud 26, which can reduce or prevent airflow blockages to maintain optimal airflow and suction power. The centrifugal force in the inner chamber portion 204 causes the finer debris material to be separated from the airflow and collected in the inner chamber portion 204. The suction source 12 then draws the air through the filter and through the suction assembly 50 to be exhausted via the exhaust outlet 54.

[0088] The rotating deflector 70 (e.g., the deflector sleeve 72, the deflecting shroud 74, or the rotating shroud 26) and/or the filter shroud 26 may be made from durable plastics or metals that can withstand the internal environment of the cleaning apparatus 10 during standard cleaning operations. The deflecting fins 34 may have a variety of configurations, such as the quadrilateral shapes, as illustrated in FIGS. 7 and 8, or triangular shapes, as illustrated in FIGS. 9 and 10, or other practicable configurations for assisting with rotation of the deflector 70 and/or deflection of debris materials.

[0089] The deflecting fins 34 may also have a variety of orientations, such as the angled orientation illustrated in FIG. 7 or the orientation parallel with the central axis 36 as illustrated in FIGS. 8-10. For example, the deflecting fins 34 may extend generally perpendicular with the airflow in the recovery tank 20. In such examples, the deflecting fins 34 being arranged perpendicular to the airflow may be more effective at rotating the rotating deflector 70 compared to when the deflecting fins 34 are parallel with the airflow. The perpendicular orientation may allow the rotating deflector 70 to rotate more easily with less airflow. The deflecting fins 34 may have a sufficient size (length, distance from outer surface 78, thickness, etc.) to be sufficiently rigid to not substantially flex or bend in response to the cyclonic airflow.

[0090] Different aspects of the deflecting fins 34 may affect performance of the rotating deflector 70 differently. For example, the height H (in mm), angle A (in degrees), length L (in mm), and inclination I (in degrees) of the deflecting fins 34 (see FIG. 7) may each affect the performance of the rotating deflector, which can be measured in air performance drop (IOW). The length L can be the distance the fins 34 extend along the shroud 26 or between the end segments 232, 234. The angle A of the fins 34 may be the orientation relative to vertical (i.e., the central axis 36). The height H of the fins 34 may be the distance the fins 34 extend outwardly, such as from the connecting segments 236 or the shroud wall 32. The inclination I of the fins 34 may be the angle of the outer edge, which can form a change in the height H from one end to the opposing end of the fins 34.

[0091] In non-limiting examples, the height H may be in a range between about 0.5 mm and about 8 mm, the angle A may be between about 25 and about 75 or between about 25 and about 75 based on the direction the fins 34 extend, the length L may be between about 10 mm and about 120 mm, and the inclination I may be between about 0 and about 45 (such that the fins 34 taper or get smaller in height H from one end to the other). In a specific non-limiting example, the height H may be about 3 mm (at the greatest height H), the angle A may be between about 45, the length L may be about 60 mm, and the inclination I may be about 30. In another specific non-limiting example, the height H may be about 3 mm, the angle A may be between about 65, the length L may be about 30 mm, and the inclination I may be about 1.9. The specific dimensions of the deflecting fins 34 may be tailored to the size of the recovery tank 20 and the size of the filter shroud 26. In this regard, the size of the deflector sleeve 72 may vary along with the size, shape, and orientation of the deflecting fins 34.

[0092] In various aspects, the inclination I may affect the performance of the deflecting fins 34 the most. The height H of the deflecting fins 34 may affect the performance (i.e., response in air drop) the second most. Accordingly, how the fins 34 extend outward may affect performance of the deflecting fins 34 and/or the rotating deflector 70 the most. Additionally, the different aspects of the deflecting fins 34 were compared to determine what aspects affected performance more than other. Based on testing, the following affected the response/air performance drop in order from most effect to least effect: inclination I of the fins 34; height H of the fins 34, combination of height H and length L; angle A of the fins 34; length L of the fins 34; combination of height H and angle A; and combination of height H and inclination I. The larger surface area (height Hlength L) may assist with the rotation of the rotating deflector or, alternatively, smaller surface area may be advantageous depending on the configuration of the separation and collection assembly 16.

[0093] The rotating deflector 70 can be a separate component (e.g., the deflector sleeve 72 with the connecting frame 230) or the shroud 26 itself (e.g., with or without the fins 34). Further, the wiper 226 can be a separate component (e.g., with the outer frame 250 and engagement features 254) or the rotating deflector 70 (e.g., from the movement of the connecting frame 230). The wiper 226 can brush or scrape dust and other fine debris material from the outer surface 78 of the shroud as the rotating deflector 70 rotates, reducing or preventing buildup of the debris material on the filter shroud 26 for maintaining increased or optimal airflow therethrough. The centrifugal force generated by the suction source 12 pushes or causes rotation of the rotating deflector 70 in the separation system 60.

[0094] The filter shroud 26 and/or rotatable component (e.g., the deflector 70 or shroud 26) may be manufactured utilizing injection molding processes for plastics or precision processes for metals, which may also be used for forming the apertures 194 in the filter shroud 26. In certain aspects, the bearing 240 may be assembled onto the filter shroud 26, and the separate connecting frame 230 may be mounted around the filter shroud 26. The assembled shroud assembly may be installed in the collection chamber 22.

[0095] The anti-tangle, rotating deflector 70 can be used in a variety of cyclonic cleaning apparatuses 10, including both residential and commercial cleaning apparatuses 10. The rotating deflector 70 may actively and continuously reduce or prevent entanglements of long and soft debris about the filter shroud 26. The deflector sleeve 72 (e.g., the separate rotating deflector 70) and/or the separate wiper 226 can actively and continuously scrape or wipe smaller debris, such as dust, from the outer surface 78 of the filter shroud 26 during rotation. This may provide continuous and increased cleanliness for maximizing the performance of the cleaning apparatus 10 and increasing airflow for the working air through the collection and separation system 60.

[0096] The rotating deflector 70 may also provide visual feedback to the user during the cleaning process. For example, when the rotating deflector 70 stops rotating during use of the cleaning apparatus 10 and the recovery tank 20 is not full or is at least partially empty, the stopped movement of the rotating deflector 70 may serve as primary or secondary feedback or notification to inform the user to clean or replace components of the separation and collection assembly 16. These components may be any, some, or all of the filters 172 in the apparatus 10. The stopped movement may be used as additional feedback in combination with loss of performance. Additionally, in more conventional arrangements, there may not be a physical cue to replace filtering components. The stopped rotation may provide this physical indication to clean or replace various components of the separation and collection assembly 16.

[0097] Use of the present device and system may provide a variety of advantages. For example, the cleaning apparatus 10 may include an anti-tangle, rotating deflector 70 that is configured to rotate with the cyclonic airflow in the recovery tank 20. The centrifugal force caused by the suction source 12 is configured to rotate the rotating deflector 70, which deflects debris materials away from the filter shroud 26 and causes the debris material to separate from the airflow. Also, the rotating deflector 70 may deflect the debris material away from the filter shroud 26 and reduce or prevent longer debris material from wrapping or tangling around the filter shroud 26. Additionally, the wiper 226 and/or the deflector sleeve 72 may brush or scrape dust from the outer surface 78 of the filter shroud 26. The rotating deflector 70 and/or the wiper 226 may maximize the efficiency of airflow through the cleaning apparatus 10 by reducing blockages caused by debris material on the filter shroud 26. Further, the rotating deflector 70 and/or the wiper 226 may decrease maintenance by the user due to reduced entangled debris around the shroud 26 and/or reduced dust on the outer surface 78. The rotating deflector 70 and/or the wiper 226 may provide increased cleanliness to components of the separation and collection assembly 16, increase the performance of the separation system 60, and enhance the overall user experience. Additional benefits and advantages may be realized and/or achieved.
