A brush device with quick couplings for cleaning elements (5) includes: first (15) and second (17) retaining elements that define respective cavities shaped approximately complementary to first (21) and second (23) matching members. The second the retaining element (17) has a tooth (27) delimiting the corresponding cavity, cantilevered onto a flexible arm (29) connecting it to a respective end of a first connection element (7) or of a second connection element (11). The flexible arm (29) has a driving extension (33) for manual actuation thereof to free the matching member (21, 23) from the tooth (27) allowing for the detachment of at least the second connection element (11) and of the cleaning element (5).

The present invention provides a cleaning unit, comprising: a columnar body part having a rotation guide opening formed on the outer circumferential surface thereof; a shaft installed to reciprocate a predetermined distance in the longitudinal direction thereof in a hollow formed in the body part; a drive part that protrudes from the shaft in the radial direction thereof; a brush part that has one side installed on the outer circumferential surface of the body part along the longitudinal direction thereof and rotates on the basis of the one side as a rotation axis; and a driven part that extends from the brush part toward the drive part, passes through the rotation guide opening, and is inserted into a rotation guide groove formed in the drive part. The rotation guide groove extends at a predetermined angle with respect to the longitudinal direction of the shaft, and as the shaft reciprocates, the driven part is guided to rotate by means of the rotation guide groove, and the brush is rotated by means of the rotation of the driven part. The cleaning unit may include a robot cleaner or a cleaner operated by means of a user's operation.

In order to provide a dust-containing gas treatment apparatus which can smoothly achieve the treatment of gas containing dust of high concentration, the apparatus is equipped with a cylindrical treatment room 1 to introduce gas containing dust and remove the dust from the gas, catcher 2 consisting of brush with the hair 22 planted in the support 21 installed in the treatment room 1 to catch the dust contained in the gas, liquid spraying mechanism 3 installed in the treatment room 1, rotary driving mechanism 6 to rotate the catcher 2 and stirrer 4, gas introducing portion 7 to introduce the gas containing dust, gas discharging portion 8 to discharge the gas, the dust removed, from the treatment room 1 and liquid discharging portion 9 to discharge the liquid containing the dust removed from the gas.

A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.

The present disclosure relates to an apparatus and a method for wafer cleaning. The apparatus can include a wafer holder configured to hold a wafer; a cleaning nozzle configured to dispense a cleaning fluid onto a first surface (e.g., front surface) of the wafer; and a cleaning brush configured to clean a second surface (e.g., back surface) of the wafer. Using the cleaning fluid, the cleaning brush can clean the second surface of the wafer with a scrubbing motion and ultrasonic vibration.

Provided is a disclosure for a brush for cleaning a surface, where the brush comprises a center core and cleaning material around the center core. Modules are found on the cleaning material, where nodule density on the cleaning material varies. Accordingly, a first nodule density of a first region of the cleaning material is different than a second nodule density of a second region of the cleaning material.

A pet hair removal apparatus has a plurality of engagement members. One of the engagement members is a squeegee that includes a textured surface. The textured surface extends transversely or laterally between first and second sides of the apparatus. The apparatus operates in a plurality of different operational engagement position in which different engagement members contact the surface to remove pet hair from the surface depending on which operational engagement position the apparatus is positioned. The pet hair removal apparatus may be formed through a coextrusion process to form the resultant shape of the pet hair removal apparatus using multiple different materials to form the engagement members and a body thereof.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. At the end of the handle is a pointed end defined by a pointed tip. The pointed end and pointed tip operates in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. The pointed end removes hair or other debris that are in or near a crease or crevice of the fabric. This operational engagement position is one of a number of other operational engagement positions for the pet hair removal apparatus.

A pet hair removal apparatus has a plurality of engagement members. The apparatus has a handle and connected base member. On the base member is one or more engagement members, such as lugs, protrusions or frustums. On the lower surface of one of the engagement members is one or more striations, ribs, squeegees or ridges. The striations, ribs, squeegees or ridges operate in an operational engagement position to remove pet hair from the surface of an inanimate object, such as a couch or other fabric. This operational engagement position for the striations, ribs, squeegees or ridges is one of a number of other operational engagement positions for the pet hair removal apparatus.

A reconfigurable vacuum attachment may include a bell-shaped housing. The bell-shaped housing may have a bell-opening and a hose-interface. The hose-interface may be configured to hydraulically couple with a vacuum hose. A skimmer-plate may be attachable to the bell-opening and include a skimmer-aperture extending through the skimmer-plate. The reconfigurable vacuum attachment may further include a removable brush assembly. The brush assembly may host a rotatable brush coupled to a brush driver. The brush driver may be configured to hydraulically couple with the vacuum hose and convert water flow into a torque and spin the bristles. A buoy may be attached to the housing allowing the reconfigurable vacuum attachment to be used as a pool skimmer. The reconfigurable vacuum attachment is useful for skimming a pool surface and dislodging and vacuuming matter from a pool wall.
