The machine includes a generally horizontal frame including a pair of depending flanges on its opposite sides. A plurality of transversely aligned rollers are rotatably mounted by the longitudinal flanges for contacting the floor and supporting the weight of the machine. A reversible handle is provided so that the machine can be pushed or pulled in either direction, and a vibratory motor is secured to the top of the frame for vibrating the rollers. A plurality of transverse strengthening channels are connected to the frame to evenly distribute the vibratory forces across all of the rollers.
