  • Patent number: 6082376
    Abstract: A method for operating an upright wet extractor having a base and a handle. The base includes a floor cleaning tool and has a hand held cleaning tool permanently attached thereto. A motor fan unit is operated to generate a suction force and this suction force is selectively communicated to a suction inlet of one of the hand held cleaning tool and the floor cleaning tool. When the suction force is communicated to the hand held cleaning tool suction inlet, pressurized cleaning fluid is also supplied to that tool, and when the suction force is supplied to the suction inlet of the floor cleaning tool, a brush unit is rotated in the floor cleaning tool.

  • Patent number: 5933912
    Abstract: An upright wet extractor includes a base assembly, a manipulative handle pivotally attached to the base assembly, and a motor driven agitator brush. A cleaning solution dispensing tank is removably attached to the handle assembly by a pivotable latch member. In a floor cleaning mode, cleaning solution is selectively supplied by gravity from the dispensing tank to a floor cleaning spray nozzle through a supply tube which is controlled by a pinch valve. In an attachment hose cleaning mode, cleaning solution is selectively supplied by a motor driven pump from the dispensing tank to an attachment hose spray nozzle which is controlled by a trigger valve. A suction motor/fan assembly is carried by the base assembly which is selectively in fluid communication with a floor suction nozzle in the floor cleaning mode and an attachment hose suction nozzle when in the attachment hose cleaning mode.
