Abstract
A vacuum cleaner includes a housing having a suction opening disposed between front and rear brushes for sucking dirt from a floor. A rag disposed behind the rear brush is rotatably driven about a transverse axis by the reciprocal action of the housing as the latter is displaced along the floor. A water supply keeps the rag moist. The rag is driven such that the floor-engaging portion is driven in a direction opposite the direction of housing travel. An auxiliary opening in the suction line sucks dirt from the rag at a location above the floor.
