A high-speed conversion for floor treating machines which comprises a wheeled frame, an impeller member attached to the floor treating drive of a floor treating machine for rotation therewith, a plurality of speed accelerators fixedly attached to the impeller member and having an end portion thereof engaging the frame and having an opposite end portion fixedly attached to a roller for engaging a floor treating element support which is rotatably journaled to the impeller member. A floor treating element such as a brush, pad, or sand paper is fastenable to the floor-facing side of the floor treating element support for rotatable engagement to the floors. In operation, the impeller member rotates at a speed up to 300 rpm and the speed accelerators rotate the floor treating element and support at speeds capable of exceeding 2500 rpm. Because of such high speeds, the high-speed floor treating elements can burnish, strip, sand paper, wax, and clean the floors more conveniently, faster, and more effectively than slower speed floor treating elements on floor treating machines not using this invention.
