The present disclosure provides a floor cleaner that includes a replaceable component, such as a brushroll or a filter. The floor cleaner has a detection mechanism comprising a magnet on the replaceable component and a Hall Effect sensor positioned to detect the permanent magnet when the replaceable component is correctly installed on the floor cleaner. Operation of one or more electrically-powered components of the floor cleaner is prevented when the permanent magnet is not detected by the Hall Effect sensor.

A surface cleaning apparatus comprises a base, a portable cleaning unit removably mounted to the base and comprising at least one air treatment member, a portable cleaning unit energy storage member and a portable cleaning unit suction motor. The portable cleaning unit suction motor is operable on power provided by the portable cleaning unit energy storage member when the portable cleaning unit is removed from the base. The surface cleaning apparatus comprises or is connectable to a power cord. When the portable cleaning unit is mounted to the base and when the surface cleaning apparatus is connected to an external source of power by the power cord, the portable cleaning unit energy storage member is chargeable on power provided by the power cord provided by the external source of power and the portable cleaning unit suction motor is concurrently operable on power provided by the power cord provided by the external source of power.

The present invention provides unique portable or stationary hose retraction systems in a single compact unit having an elongated hose, a chamber or plenum for storing the hose, a primary vacuum source for creating suction in the hose, and a secondary vacuum source for retracting the hose into the chamber. Embodiments may include one or more switches located at a distal end of the hose for controlling the primary and secondary vacuum sources. Other embodiments include a movable robotic unit with a proximity generating signal at the distal end of the hose, whereby the robotic unit may withdraw the hose as needed during use, and the secondary vacuum source may retract slack in the hose during use, or may retract the entire hose and the robotic unit after use.

A surface cleaning apparatus comprises an air treatment chamber having a first end comprising a first end wall, an axially spaced apart second end comprising a second end wall, a sidewall extending between the first and second end walls, an air treatment chamber air inlet and an air treatment chamber air outlet provided at the second end. A dirt collection region, which is contiguous with the air treatment chamber, is positioned axially from the first and second end walls and is closer to the second end wall than the first end wall.

A floor cleaner including a recovery tank. The recovery tank includes a tank body having a lower end wall, an open upper end, and a sidewall that extend upwardly from the lower end wall. A cover that includes a suction air outlet in fluid communication with a vacuum source. An inlet duct extends upwardly from the lower end wall. The recover tank includes a shutoff float including a float body and a closure. The float body is configured to float on a surface of cleaning fluid and the closure is received in the suction air outlet to close the suction air outlet. The float body moves along the inlet duct as the float body floats on the surface of the cleaning fluid. The float body includes an aperture extending through the float body and the inlet duct extends through the aperture of the float body.

A surface cleaning apparatus comprises a canister body having a recess with sidewalls that extend upwardly from a platform, the platform having a pre-motor filter housing with a pre-motor filter positioned therein, wherein at least 50% of a perimeter of the pre-motor filter is recessed inwardly from the sidewalls of the recess whereby, when a pre-motor filter is positioned in the pre-motor filter housing, a portion of the platform is visible between the perimeter of the pre-motor filter and the sidewalls of the recess. An air treatment assembly is removably mountable to the canister body and seats on the recess when the air treatment assembly is mounted to the canister body.

A surface cleaning apparatus having an upright assembly, a power source, and a coiled electrical cable. The upright assembly including a frame and a telescoping handle at last partially extending from the frame and movable between an extended position and a contracted position. The coiled electrical cable being provided within a portion of the telescoping handle and configured to uncoil or coil when the telescoping handle is moved between the extended position and the contracted position.

A vacuum cleaner includes a first tube and a second tube positioned within the first tube, where a first end of the first tube is connected to an outlet of the backbone and a first end of the second tube connected to an inlet of the backbone. A handle is on the first end of the first tube. When the backbone is in a retracted position the first end of the first tube surrounds the second end of the second tube, the second end of the second tube obstructs the outlet of the backbone, and the second end of the first tube surrounds the first end of the second tube. When the backbone is in an extended position the second end of the first tube aligns with the second end of the second tube, leaving the outlet of the backbone unobstructed to a dustcup. A floor nozzle is connected to the inlet of the backbone and includes a nozzle motor configured to operate a brush roll axle and a casing that provides an airpath to the inlet of the backbone.

A surface cleaning apparatus includes a base unit configured to be moved over a surface to be cleaned, an upper unit coupled with the base unit, and a handle coupled with the upper unit and moveable between a folded position and an upright position.

A vacuum cleaner includes: a plurality of sensors configured to generate sensor signals; a vacuum motor; and a controller comprising first and second modules, wherein: the first module is configured to process the generated sensor signals to generate a plurality of control signals; the second module is configured to process the plurality of control signals to generate an output signal indicating that the vacuum cleaner is currently being used; and the vacuum motor is configured to activate or deactivate in dependence on the output signal.
