Abstract: A carpet extractor includes a solution distributor, such as a spray bar 90, which delivers cleaning solution to a floor surface. A housing 10 selectively receives a recovery tank 22 for collecting dirty cleaning solution from the floor. A first tank 14 for concentrated cleaning fluid and a second tank 15 for clean water supply cleaning fluid and water to a reciprocating pump 420 through first and second fluid lines 412, 410. The pump includes a piston 428, which reciprocates between first and second ends of a cylindrical bore 430. A fluid line 432 interconnects the first and second fluid lines. As the pump reciprocates, a portion of the water is drawn into the interconnecting line during a downward stroke, where it mixes with the entering cleaning solution. As the pump moves on its upward stroke, the mixture is drawn back into the water line and is pushed onward by the pump toward the spray bar with each successive downward stroke.

Abstract: A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A first supply tank 14 for concentrated cleaning fluid and a second supply tank 15 for clean water are mounted on an inverted Y-shaped handle assembly 12. The handle assembly includes a central member 334 with a hand grip 336 at its upper end and two splayed leg members 338, 342, 340, 344, which define a triangular shaped gap therebetween. The two tanks are removably mounted in the gap. The cleaning fluid tank is supported on a shelf 346, which spans the gap between the leg members. The water tank is pivotally mounted on two projections 374 on the leg members to allow for easy removal and replacement on the handle. The arrangement of tanks in the gap allows for large capacity tanks, a well-balanced handle, ease of removal of the recovery tank without the need for removing either of the two supply tanks, and ease of refill of the supply tanks.

Abstract: A dirt cup latching arrangement includes a cleaner housing portion and a dirt cup mounted on the housing portion to define a mounted position. A latch assembly is pivotally mounted to the housing portion. A catch frame is pivotally mounted to the housing portion in spaced relation to the latch assembly. The latch assembly and the catch frame cooperate to selectively secure the dirt cup to the housing portion. A tool storage arrangement can include a cap pivotally mounted to the housing with the cap having an upper surface and a lower surface. At least one indentation is located on the cap upper surface and is shaped for accommodating an associated cleaning tool of the vacuum cleaner.

Abstract: A carpet extractor includes a base assembly 1 including a housing 10 which selectively receives a recovery tank 22 for collecting dirty cleaning fluid. A nozzle assembly 67 is mounted to the base housing and provides a fluid flowpath 182 for dirty cleaning fluid from the floor surface to the recovery tank. The nozzle assembly is pivotable from a first position, in which the fluid flowpath communicates with the recovery tank, to a second position, in which the nozzle assembly is spaced from the recovery tank to allow the recovery tank to be removed from the base housing. A second flowpath 138 is formed on the recovery tank between the tank and a nozzle plate 136. The flowpaths have openings 218, 140, respectively, at their lower ends, which are located either side of two longitudinally spaced brushrolls 60, 62. A flap valve 474 selectively closes both flowpaths during above floor cleaning.

Abstract: A vacuum cleaner includes a cyclonic airflow chamber that facilitates the separation of contaminants from a suction airstream. The airflow chamber includes a chamber inlet and a chamber outlet, with the chamber inlet being fluidically connected with at least one of a suction nozzle and an above-the-floor cleaning tool. An exhaust filter housing includes a suction duct and an exhaust plenum, with the suction duct communicating with the chamber outlet. A suction source housing includes an open end communicating with the exhaust plenum and a closed end. A suction source is positioned within the suction source housing to define an annular exhaust flow passageway surrounding the suction source from the housing closed end to the housing open end. The suction source includes a suction inlet communicating with the suction duct and an exhaust outlet communicating with the housing closed end.

Abstract: A turbo tool includes a housing forming a hollow section. The housing includes at least one air inlet and a nozzle opening spaced from the air inlet, a brushroll rotatably mounted in the housing and within the nozzle opening and a turbine. The turbine is drivingly connected to the brushroll for rotating the brushroll. The turbine is driven by a first airflow through the air inlet. A rotational axis of the brushroll is parallel to a longitudinal axis of the turbine and parallel to a longitudinal axis of the housing. A first conduit is located in the housing and connected to the nozzle opening. A second airflow occurs through the first conduit. A second conduit is fluidly connected to the first conduit and to a third conduit. The first and second airflows merge into the second conduit. A swivel attachment is connected to the third conduit and swivels the housing between two positions approximately 180 degrees apart and is locked into one of the two positions.
