Abstract: A mop comprising an elongated handle having an oblong sponge mounted on one end for washing a flat surface such as a floor or window. A housing is mounted on the elongated handle above the oblong sponge. The handle is provided with a device for selectively retracting the sponge into the housing and simultaneously wringing the sponge. A wiper blade is mounted on the housing and is positioned to wipe the surface being mopped when the sponge is retracted within the housing. A roller is mounted to the mop and has a removable covering of absorbent, washable material. The roller contacts the surface being mopped and dries the surface when the sponge is retracted within the housing. The device eliminates all traces of water and soap residue from the mopped surface and thus eliminates unsightly water marks and streaks.
