A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A surface cleaning apparatus such as an extractor has a fluid flow path extending from a dirty fluid inlet head to a clean air outlet. The fluid flow path upstream of the separation stage comprises a removable portion.

A shop vac includes a handle, a canister, a vacuum tube, and a pick-up device. The canister holds an enclosure that generates a negative pressure by forcing compressed, high velocity air through a orifice plug and out a muffler to create a vacuum in the enclosure. The vacuum in the enclosure is transferred to the vacuum tube and the pick-up device to pick up liquid or debris on a shop floor. The enclosure inside the canister includes a flow control valve such as a ball in cage device to prevent fluid from entering the enclosure. An evacuation spout is located at the bottom of the canister for draining the vacuum when the canister becomes full.

A floor cleaning machine for cleaning a floor surface includes a recovery tank having an inlet conduit and a flow divider. The flow divider includes a divider inlet in downstream fluid communication with the inlet conduit. The flow divider divides the flow into at least two separate flow paths. Each separate flow path includes a first flow path portion for directing the flow in a first direction away from the divider inlet, a second flow path portion directing the flow in a second flow direction that is substantially different from the first flow direction, and a flow redirector portion for redirecting the flow from the first flow direction to the second flow direction. The recovery tank also includes a tank body in downstream fluid communication with the flow divider. The tank body collects dirty fluid from the floor surface.

A wet-dry vacuum cleaner including a collecting bin and a power head removably coupled to the collecting bin. The power head includes a housing configured to support the power head on the collecting bin, an exhaust outlet, and a cyclonic separator positioned within the housing. The cyclonic separator includes a dirty air inlet, a chamber, and a clean air outlet. The power head further includes a suction motor assembly operable to create a working airflow path from the dirty air inlet to the exhaust outlet, and a filter disposed within a filter housing hanging downwardly from the suction motor assembly. The filter is positioned within the working airflow path adjacent the clean air outlet of the cyclonic separator.

A surface cleaning apparatus includes a heated vapor generator for generating steam and a supply tank for containing a supply of fluid. A liquid conduit that is in fluid communication with the supply tank is in heat exchange relationship with a vapor conduit that is in fluid communication with the heated vapor generator.

A dust collector has a well-balanced weight. The dust collector includes a body housing, a motor located inside the body housing, a fan rotatable by the motor, and a battery mount located inside the body housing and frontward from the motor.

An improved shop vacuum with wet/dry capability uses a vacuum tube that terminates in a space between the canister and the vacuum compartment such that the substance and content exiting the vacuum tube is not directly opposed the negative pressure source. This allows the substance to drain into the canister in a more controlled and less volatile condition, reducing splashing and entrainment of the substance. Moreover, a second exit for the vacuum has been added to the canister to improve the efficiency of the vacuum and the overall performance of the device.

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 dust collector includes a filter frame, a cartridge filter, an end cap, and a cover. The filter frame is provided with a center column. The end cap is provided with a bottom plate, a plurality of sliding slots, a plurality of first side walls, a plurality of baffles extending from the first side walls, and a plurality of clamping members. The cover is provided with a plurality of protruding members and a plurality of extending members. The filter frame includes an accommodating space. The bottom plate is provided with a plurality of through openings that run through the bottom plate. The through openings are disposed opposite to the baffles and are configured to communicate between the sliding slots and the accommodating space. The extending members extend into the through openings. The first side walls are connected between the bottom plate and the baffles.
