Surface treating device
First Claim
1. A power operated surface treating device comprising a handle assembly, a generally cylindrical roller, means supporting said roller on said handle assembly for rotation about its axis and relative to said handle assembly, drive means for rotating said roller about said axis and relative to said handle assembly and including a motor supported within said roller and having a fixed part and a rotatable part, one of said parts comprising said fixed part and said rotatable part being connected to said handle assembly and the other of said parts being connected to said roller, a power supply source wholly contained within said roller, and switching means on said surface treating device for connecting said power supply source to said motor to energize said motor.

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 to expell waste liquid from the applicator sleeve which is collected and stored within a waste liquid container associated with the handle assembly.

21. A power operated surface treating device comprising a handle assembly including a frame and a handle projecting from said frame, a roller assembly including a hollow generally cylindrical roller and a generally cylindrical absorbent applicator sleeve coaxially received on said roller, means for supporting said roller assembly on said frame for coaxial rotation relative to said frame, a drive motor contained within said roller, a power supply source contained within said roller for operating said drive motor to rotate said roller about its axis and relative to said frame, fluid passageway means defined by said frame for discharging liquid above and onto said absorbent sleeve along a substantial portion of the axial length of said sleeve, a fluid reservoir assembly releasably secured to said handle assembly in fluid communication with said fluid passageway means for containing a quantity of treating liquid, and manually operable valve means for releasing treating liquid from said reservoir assembly into said fluid passageway means.
