Abstract
A portable power operated surface cleaning device comprising a handle assembly, a hollow generally cylindrical roller supported for rotation on and relative to the handle assembly, and an absorbent generally cylindrical applicator sleeve coaxially supported on said roller for rotation therewith. The roller is driven by an electrical motor contained within it and powered by a rechargeable battery also supported within the roller. Operation of the motor is controlled by a rotary electrical switch which includes a pair of magnetically responsive electrical switch contacts contained within the roller and a magnetic switch actuator mounted on the handle assembly. A reservoir assembly releasably secured to the handle assembly contains a supply of cleaning solution which is released from the reservoir assembly for gravity flow through passageways in the handle assembly and onto the applicator sleeve along a substantial portion of the axial length of the applicator sleeve in response to operation of a manually controlled valve associated with the reservoir assembly. A manually operated wringer supported on the handle assembly is movable into squeezing engagement with the applicator sleeve …
