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.

Abstract: An apparatus for adjusting a height of a suction brush for use in a vacuum cleaner includes a height adjusting knob rotatably disposed in an inserting recess formed in the suction brush, and having an inclined part formed thereon, so that a height of the suction brush from a surface to be cleaned is varied as a position of the height adjusting knob rotated, a supporting member to support the suction brush in contact with the inclined part thus to allow the suction brush to be ascended and descended by the inclined part, and a passage disposed between an inner circumferential surface of the inserting recess and an outer circumferential surface of the height adjusting knob to pass fine dirt therethrough. With the passage, the fine dirt is not tied up between the inner circumferential surface of the inserting recess and the outer circumferential surface of the height adjusting knob. Accordingly, the rotation of the height adjusting knob is not restricted or obstructed due to the fine dirt.

Abstract: A floor care appliance is provided with a microprocessor based control arrangement. The microprocessor adjust the height of the suction nozzle through a motorized suction nozzle height gear and cam arrangement. The microprocessor is programmed to turn the current off to either of the motor-fan assembly or the agitator drive motor when the current consumed by either exceeds a predetermined amount based upon the nozzle height. The height of the suction nozzle is selected by one or more switches located on the appliance handle. A separate switch is provided to select bare floor mode and the microprocessor is programmed to store the height of the suction nozzle prior to bare floor mode being selected. By pressing a the bare floor mode button again or the use of a sensor the suction nozzle is returned to the stored position when the suction nozzle is returned to the carpeted surface.

Abstract: A floor care appliance such as a vacuum cleaner is provided having a traction wheel powered edge cleaner comprised of a vertical axis rotary agitator which is affixed to either the right or left side of the suction nozzle. The agitator is rotated by the traction wheel when the vacuum cleaner is disposed along a wall surface and moved relative to the wall surface. The rotating action of the agitator sweeps dirt particles off of the wall surface and along the edge of the wall surface into the path of the suction nozzle for pickup. When not in use the edge cleaner is stored in the accessory storage rack like other accessory tools. The agitator can have differing agitator elements such as bristles or a fluff wheel.

Abstract: A cleaning apparatus includes a top cover and a seat that together form a main body of the apparatus, and a wheel adjusting mechanism mounted between the top cover and the seat. The wheel adjusting mechanism includes a lifting gear, a braking gear, and a pair of wheels connected to two ends of an axle. When the lifting gear is downward pushed to press against the axle and a catch provided on the lifting gear is engaged with a hooking portion on the braking gear, the cleaning apparatus is lifted by a predetermined distance. When the braking gear is forward pushed and the hooking portion is disengaged from the catch on the lifting gear, the cleaning apparatus is lowered to an initial position thereof.

Abstract: A floating cleaner head used with a self-propelled front wheel drive floor cleaning apparatus, such as a vacuum cleaner. Both the forwardly located drive wheels and the drive transmission therefor are pivotably mounted on a bracket beneath the cleaner head. A skid plate attached to the bracket extends rearwardly from the bracket pivot to sense the carpet pile height of a floor to be cleaned. As the pile height increases, the bracket is pivoted so as to force the drive wheels deeper into the carpet pile which increases the propelling force. Additionally, since the drive wheels and transmission are located intermediate freely-rotatable rear wheels and a forwardly located rotary brush and nozzle area, operation of the skid plate also cause the entire cleaner head to float or pivot about the axis of the rear wheels so as to automatically adjust the elevation of the rotary bar and nozzle area.
