Abstract: A floor cleaner comprising a base and a filter bag housing, the filter bag housing having a bag cavity which has an undulated inner wall for receiving a filter bag, the undulated wall having a plurality of elongated protrusions and adjacent intermediate elongated air flow recesses. A smooth outer wall is spaced from the inner wall.

Abstract: A vacuum cleaner comprising a housing having an elongated transverse brush cavity with an elongated cylindrical brush therein, a duct having an air flow nozzle adjacent the brush cavity for receiving dirt-entrained air from the brush cavity, a vacuum motor operably associated with the duct and nozzle to draw dirt-entrained air through the nozzle and duct, and the brush cavity having a wrap configuration geometry over the brush including an elongated reflective ledge angled laterally upwardly toward the nozzle.

Abstract: An upright floor cleaner comprising a base, an upper housing and an operation handle, the upper housing and handle being pivotally mounted relative to the base, between an upright at rest condition and a lowered operation condition, the handle in the upright condition projecting upwardly above the housing and curving through an arc to a generally horizontal orientation, and in the operation condition extending diagonally rearwardly-upwardly and then curving through the arc to a generally vertical downward orientation.

Abstract: A carpet maintainer comprising a mobile support having power drive for advancing the support over an underlying carpet surface, a housing on the support, a cleaning solvent vessel on the support, a discharge spray bar at the support underside for discharging cleaning solvent from the vessel onto an underlying carpet surface, a pair of powered, counter-rotational, elongated brushes at the support underside, adjacent each other, and transverse to the support, the spray bar being forward of the brushes for ejecting cleaning solution on the carpet followed by brush scrubbing and pile pick-up of the carpet, a debris hopper, a suction fan in the housing, an air and debris conducting conduit extending from the hopper to the suction fan, and a collector bag between the hopper and suction fan so that dirt and debris swept up by the brushes is deposited in the hopper or drawn by the fan into the collector bag.

Abstract: A floor burnisher having a frame, a peripheral housing, rear wheels and a front caster, the housing having an internal cylindrical wall defining a vertical chamber having an open bottom; a floating rotational drive motor in the chamber, and a rotational pad-driver underlying and connected to the motor to be rotationally driven thereby for mounting a flexible burnishing pad; suspension links and springs between the frame and drive motor suspending the drive motor, pad-driver and pad thereon in a floating fashion relative to the frame and housing, allowing limited vertical movement relative to the cylindrical wall; a flexible, peripheral, floor-engagement skin suspended from the peripheral housing shroud, and an air flow control sealing member between the motor and annular wall for preventing excessive air flow between the floating motor and wall into the burnisher wall chamber.
