ABSTRACT:
A cleaning device for floors or walls, in which water or similar cleaning fluid is continuously applied to the work surface as the device moves along that surface. A power-driven rotary brush is located to exert a scrubbing action on the applied water film so as to assimilate dirt particles into the water film. The dirt-laden water is removed from the work surface by two power-driven rotary sponges located directly behind the rotary brush. A sponge compression structure is engaged with an upper surface of each sponge to continuously water absorbed by the sponges.
