ABSTRACT:
An apparatus for imparting a high gloss to a floor including a frame, a motor mounted on the frame, a drive pad operatively rotated by the motor, a buffing pad positioned beneath the drive pad and rotated at about 2200 RPM thereby, and an adjustable shield mounted on the frame. The drive pad is partly and centrally concave such that only a relatively small outer surface area of the drive pad is supported by and drives the buffing pad. Preferably, only about the outer 15% of radius of the drive pad includes engaging projections or the like thereon to engage the buffing pad. The shield is adjustable to allow a lower edge to be placed relatively very close to the floor to prevent the buffing pad from engaging debris, walls or the like and to reduce the amount of dust raised in the air by the polishing. The adjustability of the shield allows for variance in thickness of the buffing pad due to wear or the like.
