Abstract: An upright deep cleaner including a base housing pivotally connected to an upright handle, the upright handle carrying a liquid supply tank and the base housing including a recovery tank. The liquid supply tank includes an internal siphon tube for ensuring liquid flow to a feed valve when the upright handle is in the inclined position. The base housing includes a suction nozzle adjacent a spray bar, and removable floating brush for contacting a surface being cleaned, the brush being interchangeable with a bare floor tool including a sponge, brush, and squeegee. The recovery tank includes an internal baffle for preventing foaming of solution and a tank vent housing including a sponge-type filter to prevent spray from exiting the recovery tank. A vacuum motor cooling outlet is positioned on underside of the base housing to distribute air heated by the motor onto the surface to be cleaned.

Abstract: An surface cleaning implement comprises a recovery tank and a suction nozzle in fluid communication with a recovery tank, a fan/turbine assembly including a turbine-driven suction fan for generating suction at the suction nozzle, which draws liquid and air into and through the accessory tool. A fluid dispensing assembly is disclosed for storing and distributing fluid to the surface to the cleaned. An agitator assembly can be moved from a use to a non-use orientation to alternately scrub the surface to the cleaned and to extract fluid from the surface to be cleaned.

Abstract: An upright vacuum cleaner comprises a base assembly pivotally connected to an upright assembly. The base assembly comprises housing, a support, and ratchet-operated nozzle height adjustment mechanism for raising or lowering a suction nozzle on the base assembly relative to a surface to be cleaned.

Abstract: A wet/dry canister vacuum cleaner has a base assembly, a recovery tank, and a solution tank. A hose interface adapted to mount a vacuum hose is pivotally mounted on the base assembly for selective fluid communication with the inlet to the recovery tank. The hose interface is moveable between a position in which the hose interface is coupled with the recovery tank and a suction source in fluid communication with the recovery tank can draw fluid through the hose interface and the recovery tank, and a second position, in which the hose interface is removed from the recovery tank and the recovery tank can be removed from the vacuum cleaner without having to disconnect the vacuum hose from the vacuum cleaner. The vacuum cleaner can further comprise a diverter assembly for switching between dry and wet mode cleaning, where the diverter assembly forms an inlet to the recovery tank.

Abstract: An accessory tool according to the present invention comprises a recovery tank assembly for removing fluid and dirt from a surface to the cleaned and storing the recovered fluid and dirt. The recovery tank assembly comprises a suction nozzle in fluid communication with a recovery tank. The accessory tool further comprises a fan/turbine assembly including a turbine-driven suction fan for generating suction at the suction nozzle, which draws liquid and air into and through the accessory tool. The turbine-driven suction fan can be magnetically coupled with the turbine. The accessory tool can further comprise a fluid dispensing assembly for storing and distributing fluid to the surface to the cleaned. The fluid dispensing assembly can comprise a turbine-driven fluid pump.

Abstract: A vacuum cleaner has cooling air from an agitator motor ported to a working air conduit upstream of an inlet to a fan motor assembly.

Abstract: A liquid extraction cleaner includes a solution dispensing system, a liquid recovery system, and an agitation brush assembly. The solution dispensing system includes a supply tank removably affixed to a housing and fluidly connected to a fluid distributor through a trigger-operated manual spray pump. The liquid recovery system includes a recovery tank removably mounted to the housing adjacent to the supply tank. An air liquid separator is provided within the recovery tank. Another assembly within the housing provides a vacuum source, where working air comes from the recovery tank to an inlet between a motor and an impeller. The agitation brush assembly is removably mounted in a lower forward portion of the housing.

Abstract: A portable extraction cleaning machine has a housing assembly including a housing enclosure centrally mounted on a housing base and a handle adapted for user carrying of the extraction cleaner, a suction motor and impeller assembly sealed within the housing enclosure and a solution tank for cleaning solution and a recovery tank removably mounted to the housing base in a fore and aft position. The recovery tank has an integrally molded spout and an air/liquid separator comprising a riser tube having an internal divider separating the riser tube into fluidly isolated first and second conduits. A plurality of different decorative face plates are adapted to be removably mounted to the housing enclosure and each of which is adapted to cover at least a substantial visible portion of the visible surface of the housing enclosure when mounted on the housing enclosure.

Abstract: A liquid extraction cleaner comprises a solution dispensing system, a liquid recovery system, and an agitation brush assembly. The solution dispensing system includes a cleaning solution supply tank affixed to the cleaner and fluidly connected to a solution spray nozzle through a trigger-operated manual solution spray pump. The supply conduit interconnecting the cleaning fluid supply tank and the spray nozzle traverses a passage formed integrally with the air-liquid separator housing, spray nozzle being mounted in the passage at a front portion of the cleaner. The liquid recovery system includes a air-liquid separator fluidly connected with a suction nozzle and a suction source for drawing liquid and debris into the air-liquid separator, and a recovery tank releasably mounted to the air-liquid separator for collecting recovered liquid. The agitation brush assembly is mounted in a lower forward portion of the cleaner for contact with a surface being cleaned.
