  • Patent number: 5455980
    Abstract: A reversible mop that includes a frame formed of a solid block of material presents two supporting horizontal surfaces having a centrally mounted, pivotally attached handle. The mop is easily reversible by simply rotating the handle through an interruption in the frame block, to select one side or the other side as the floor-facing surface. In either of the orientations, the mop presents a flat surface over substantially the entire surface of the mop. This maximizes the amount of contact with the floor for better mopping action. The handle may be attached to the central pin by a releasable coupling having a central pivot. The pivot provides the user of the mop with the ability to swing the mop from left to right, thereby increasing the utility of the mop when it is applied to large surface areas.
