A surface cleaning apparatus for cleaning a surface includes a recovery tank with a lower portion with a bottom wall that defines an opening and an extraction nozzle that is in fluid communication with the recovery tank. A motor/fan assembly is in fluid communication with the extraction nozzle and the recovery tank to generate a working airflow to transport debris-containing fluid including air and liquid from the extraction nozzle into the recovery tank. The surface cleaning apparatus also includes an air/liquid separator assembly that is selectively insertable into the recovery tank. The air/liquid separator assembly includes a riser tube with a liquid conduit integrally formed with an air conduit and a float assembly that is operably coupled with the air conduit. A coupling joins the air/liquid separator assembly with the recovery tank.

A spot cleaner apparatus may have a clean fluid tank configured for holding a cleaning fluid. A dirty fluid tank may include an integrated liquid/air separator. A cleaning head may be fluidly coupled to the clean fluid tank, the cleaning head including one or more vacuum inlets and a fluid-nebulizing orifice configured to dispense the cleaning fluid in a mist-like fashion. A pump assembly may fluidly couple the clean fluid tank to the cleaning head. A fluid heater heats the cleaning fluid at or between the clean fluid tank and the fluid-nebulizing orifice. A vacuum assembly configured for drawing a vacuum airflow from one or more vacuum inlets in the cleaning head through the integrated liquid/air separator in the dirty fluid tank.

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.

An attachment to a portable vacuum or blower device that allows a user to direct the items collected by the portable vacuum or blower device to a separate container in an easy to carry assembly. The attachment to a portable vacuum or blower device has an adapter, an inlet and outlet assembly, and a lid. The lid detachably couples to a bucket or other container allowing the user to discard the bucket and collected items entirely or store the bucket with the collected items, depending on the items collected. The adapter provides attachments to popular portable vacuum or blower devices.

A lid system for a wet-dry vacuum includes a lid shaped to cover an open end of a container and having a vacuum opening therethrough, and a hatch that engages the lid to cover and seal the vacuum opening when in a closed position and disengages from the lid in an open position to uncover the vacuum opening. A vacuum generator is mounted on the hatch, and a flanged filter is mounted on the lid and extends through the vacuum opening such that the flange supports the filter on the lid. When the hatch is in the closed position, the hatch compresses the flange against the lid to form an airtight seal between with the upper surface of the lid, and the vacuum generator communicates with the interior of the container. When the hatch is in the open position, the filter is insertable into and removable from the vacuum opening.

A flange unit for a filter unit for positioning in a water treatment device, the water treatment device including a water reservoir and a suction head. The flange unit includes a base plate having a central recess for accommodating a filling piece of the suction head, a connecting unit for detachably connecting the flange unit to an inner side of the water reservoir, a closure element for closing the recess, and a handle unit for detaching the connecting unit from the flange holding device and for carrying the filter unit.

A portable surface cleaning apparatus for a floor surface includes a main housing assembly adapted to be hand carried by a user, the main housing assembly carrying a fluid delivery system adapted for storing cleaning fluid and delivering the cleaning fluid to the surface to be cleaned, and a fluid recovery system adapted for removing the cleaning fluid and debris from the surface to be cleaned and storing the cleaning fluid and debris that was recovered, the main housing assembly comprising a base housing, a supply tank received on the main housing assembly, a recovery tank received on the main housing assembly separately from the supply tank.

The disclosed preferred embodiment of the handrail cleaning device comprises a flexible bar which uses spring resilience force to press one or more reusable or disposable cleaning pads against the moving handrail of an escalator. The apparatus provides a lightweight, low cost apparatus that is simple to set-up and use and requires no external power. Additionally, the device is capable of cleaning and treating the handrails of common escalators during operation of the escalator. The device utilizes the motion of the escalator to perform the cleaning action. The simplicity of the device allows for multiple devices to be used simultaneously by a single operator.
