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. Depressing the foot pedal once rotates the mode indicator to a first position which toggles the switch from the off position to the on position. When rotated into this position, an first indicating portion on the mode indicator is rotated underneath a first viewing window formed in the hood of the cleaner foot. Depressing the foot pedal another time rotates the mode indicator to a second position which toggles the switch from the on position to the off position. A second indicating portion on the mode indicator rotates underneath a second viewing window formed in the hood of the foot. At the same time the first indicating portion is rotated out of sight of the first viewing window.

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. A turbine rotor is rotatably connected to the nozzle body and operatively connected to the agitator

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.

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.

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. Furthermore, the power switch the power button are operatively interconnected when the upper handle assembly is attached to the bag housing.
