Abstract: An extractor cleaning machine includes a base having a distribution nozzle and a suction nozzle, a suction source in fluid communication with the suction nozzle, a recovery tank removably coupled to the base and having a recovery tank handle, an extractor handle pivotally coupled to the base, and a supply tank coupled to the extractor handle for pivotal movement with the extractor handle with respect to the base. At least a portion of the supply tank is positioned above and over the recovery tank in a direction normal to a surface to be cleaned when the extractor handle is in an upright storage position. The supply tank is in fluid communication with the distribution nozzle to supply cleaning fluid to the distribution nozzle. The extractor cleaning machine is liftable by the recovery tank handle when the extractor handle is in the upright storage position.

Abstract: A surface cleaning suction type appliance comprises a housing, an airstream suction source, a cyclone main body, and a dirt cup. The housing includes a main suction opening. The airstream suction source is mounted to the housing and includes a suction airstream inlet and a suction airstream outlet. The suction source selectively establishes and maintains a flow of air from the main suction opening, via the airstream inlet, to the airstream outlet. The cyclone main body is supported by the housing and is in communication with the main suction opening. The cyclone main body has a uniform outer circumference and includes a first stage separator, and a plurality of downstream second stage separators. The lengths of the second stage cyclonic separators are different for any number of adjacent pairs of separators from on pair up to all adjacent pairs of separators. The dirt cup is connected to the cyclone main body. The dirt cup includes a first particle collector and a second particle collector.

Abstract: An extractor cleaning machine including a base or foot movable along a surface to be cleaned and a handle pivotally coupled to the foot for movement between an upright position and a reclined position. The handle includes a tank tray having an inlet and a drain. A channel communicates with the drain and extends away from the tank tray. A distributor communicates with the inlet and is operable to distribute cleaning fluid to the surface. A supply tank is removably coupled to the handle and has an outlet in fluid communication with the inlet when the supply tank is coupled to the handle. The supply tank is at least partially supported by the tank tray and the tank tray is configured to collect fluid spilt from the supply tank and to divert the fluid away from the tank tray by way of the channel.

Abstract: An extractor-type surface cleaning machine includes a base or foot having a suction nozzle and a handle that is pivotally coupled to the foot and moveable between upright and inclined positions. The recovery tank is removably securable to the foot and fluidly communicates with the suction nozzle and the accessory. The recovery tank defines a collection chamber and a passage having an inlet in communication with the suction nozzle and an outlet. A valve member is moveable between a closed position substantially covering the outlet and an open position. Movement of the handle to the upright position moves the valve member to the closed position to block the passage during cleaning with the accessory hose. Movement of the handle to the inclined position allows movement of the valve member to the open position so that suction from the collection chamber is communicated to the suction nozzle for floor cleaning.

Abstract: An extractor cleaning machine includes a supply tank assembly having a first tank and a second tank. The first tank is in fluid communication with a distributor. The first tank has a rigid body defining a first storage chamber for storing a first cleaning fluid and supplying the first cleaning fluid to the distributor. The second tank is positioned within the first storage chamber of the first tank in fluid communication with the distributor. The second tank has a rigid body defining a second storage chamber for receiving a second cleaning fluid and supplying the second cleaning fluid to the distributor. At least a portion of the rigid body of the second tank defines a boundary of the first storage chamber to separate the first cleaning fluid and the second cleaning fluid.

Abstract: A bagless canister vacuum cleaner includes a selectively removable dirt cup, and an airstream flows rotationally through the dirt cup between an interior wall of the dirt cup and a filter assembly selectively mounted in the dirt cup so that entrained contaminants are separated from the airstream flowing through the dirt cup and collected by the dirt cup. The filter lies substantially parallel to the support surface on which the vacuum cleaner is supported. A cover member is connected to the main housing, and the cover member is selectively movable to and held in an operative position in covering relation with an open first end of a dirt cup. The main housing defines a base conformed to self-support the main housing on a support surface with the dirt cup arranged with its open first end at a higher elevation than its closed second end. The removable dirt cup includes a handle adapted for being held by a user, and the dirt cup defines or includes a spout to facilitate emptying dirt therefrom.

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 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: An upright vacuum cleaner includes an upright housing section and a nozzle base section. A cyclonic airflow dirt and dust separating chamber is defined in the upright housing section. A suction source pulls air and entrained dirt, dust, and other contaminants through a main suction opening formed in the underside of the nozzle base section and into the cyclonic airflow chamber. The cyclonic airflow chamber causes the suction airstream to travel in a cyclonic path such that the entrained contaminants are separated therefrom and deposited into a dirt container that defines the chamber. A main filter element filters residual contaminants from the suction airstream between the chamber and the suction source. An exhaust filter housing includes an airstream suction duct in fluid communication with an outlet of the airflow chamber and an inlet of the suction source. An outlet of the suction source is in fluid communication with an exhaust plenum of the exhaust filter housing.
