Abstract
The specification discloses a floor treating machine in which a vertical axis rotating brush is coupled to the motor through a motor gimbal having convex bottom and side walls which are seated in a cavity within a receiving brush gimbal, the bottom and side walls of the cavity having radii greater than the radii of the motor gimbal bottom and side wall so that the brush is free to shift its axis of rotation vis-a-vis the axis of rotation of the motor gimbal to thereby accommodate deviations in the surface being cleaned.
