  • 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.

  • Publication number: 20090320233
    Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing.
