Method and apparatus for treating a floor surface with zero-tolerance edging

Abstract

A method and apparatus is provided for treating a floor surface with zero-tolerance edging. The apparatus includes a frame and wheels mounted to the frame so the frame can travel over the floor surface. The apparatus also includes a motor mounted to the frame and a head assembly including a bottom plate. The bottom plate is operatively coupled to the motor so that the bottom plate is configured to rotate about a first axis. The bottom plate is positioned such that a tooling plate mounted to the bottom plate is configured to treat the floor surface including an edge of the floor surface intersecting a wall surface.
