  • Patent number: 7673370
    Abstract: The invention is a bare floor cleaning appliance provided with a foot pedal for raising and lowering the suction nozzle while simultaneously energizing and de-energizing the independent drive motor powering a horizontal axis rotary agitator. The foot pedal is depressed once to lower the suction nozzle to a position closest to the floor surface and the horizontal rotary agitator is energized to clean the floor surface. Suction from the motor-fan assembly is used to pick up dirt and used cleaning solution. The foot pedal is depressed one more time to raise the suction nozzle from the floor surface and de-energize the horizontal rotary agitator. In this mode, suction from the motor-fan assembly is used to pick up dry objects including dirt. The foot pedal operates the switch for energizing and de-energizing the independent electric motor by rotating a mode indicator operably connected to the foot pedal.

  • Patent number: 6711777
    Abstract: A suction cleaner nozzle has a nozzle body enclosing an agitator chamber, which has an elongated suction inlet opening. An agitator is disposed in the agitator chamber such that the agitator extends partially through the suction inlet opening for agitating a surface to be cleaned. A duct is connected to the nozzle body and located adjacent the agitator chamber. The duct extends parallel to the rotative axis of the agitator.

  • Patent number: 6314610
    Abstract: A bag housing assembly for a vacuum cleaner includes a rear bag housing which forms a bag cavity and a bag door which releasably attaches to the rear bag housing for enclosing the bag cavity. One of the rear bag housing and bag door is formed of a semi-rigid flexible fabric material which is permeable to air and which is sufficiently rigid to retain a molded shape. The flexible fabric material is attached to a rigid frame member which allows the bag door to releasably attach to the rear bag housing.

  • Patent number: 6108862
    Abstract: A self propelled upright vacuum cleaner is provided that has at least one drive wheel, a transmission for selectively driving the drive wheel in forward and reverse and propelling the cleaner in forward and reverse over a floor. A bag housing pivotally connected to the floor engaging portion. An electric power switch located adjacent to a top of the bag housing. A control link extending from the transmission and up the bag housing, with a top end of the control link being located adjacent to the top of the bag housing. An upper handle assembly having a hand grip reciprocally mounted thereon and a power switch button mounted thereon. The lower end of the upper handle assembly is adapted for connection to the top of the bag housing, such that the upper end of the control link and the hand grip are automatically interconnected when the upper handle assembly is attached to the bag housing.

  • Patent number: 5867857
    Abstract: A gravity feed liquid cleaning solution supply system particularly suitable for use on an upright hot water carpet extractor having a free floating brush assembly is disclosed. The unique system generally comprises a stationary fluid supply manifold positioned above a free floating brush assembly having multiple laterally disposed rotary brushes rotatable about vertical axle shafts suspended from a laterally disposed brush support beam. The support beam includes open top troughs, one above each individual brush, into which liquid cleaning solution cascades from the overhead manifold. From each fluid trough, the cleaning solution is conveyed to the center cup of an associated rotary brush through a conduit integrally molded into the brush support beam. By this unique structure liquid cleaning solution is supplied to the free floating brush assembly without restricting the floating movement of the scrubbing brushes over the surface being cleaned.

  • Patent number: 5761763
    Abstract: A novel upright, hot water carpet cleaning extractor is disclosed. The overall configuration and operation of the extractor is similar to that of a typical upright vacuum cleaner and may be similarly operated in both the forward and reverse direction. The herein taught extractor comprises a base frame including the floor suction nozzle, suction fan, cleaning solution distributor, and a removable combination air/liquid separator and recovery tank. A manipulative push-pull handle is pivotly attached to the base frame having a removable cleaning solution supply tank supported thereon. The herein taught upright extractor is easily stored, self contained, easy to operate and requiring minimal effort by the operator.

  • Patent number: 5713103
    Abstract: A vacuum cleaner conversion arrangement is disclosed which, particularly, may be advantageously applied to a dirt cup cleaner. In this application, the conversion hose confluently communicates with the dirt cup when the cleaner is in converted condition so that suction air flows from the dirt cup to the motor-fan system of the vacuum cleaner in either of its floor or hose modes of operation. The conversion arrangement generally includes a conversion adapter having a closure means for sealing off its conversion hose and stanchions for conveniently mounting the ends of the same hose when it is not in use. The closure means may take the form of an outer door or an internal flapper valve plate.
