  • Patent number: 4604767
    Abstract: A wringer sponge mop and scrubber attachment, the scrubber attachment carrying a detachable scrubber pad. The scrubber attachment may be fashioned of wire, sheet metal, a rigid plastics material or any desired combination of these materials. In the normal or use position of the sponge, the scrubber pad is positioned on one side of the sponge and rearwardly of the sponge working (floor or wall contacting) face. In the sponge wringing or squeezed position of the mop, the sponge is retracted and the scrubber pad rotates to move forwardly of the retracted sponge working face, now able to be applied to a floor or wall to be abrasively rubbed. This combination yields a mop capable of both cleaning, by brushing a liquid laden sponge over a surface, and of abrasively rubbing to effect further cleansing treatment of a surface.
