<p>Apparatus for treating a floor surface has a drive motor with a drive shaft rotatable on a rotation axis, and a drive assembly drivingly connected to the drive shaft for conjoint rotation therewith. A floor surface treatment device is releasably connected to the drive assembly for conjoint rotation therewith about the rotation axis of the drive shaft. The floor surface treatment device is adapted for engagement with the floor surface to treat the floor surface upon rotation off the device relative to the floor surface. In a preferred embodiment, the drive assembly has a set of gear teeth and the floor surface treatment device has a corresponding set of gear teeth and is sized relative to the drive assembly to permit driving interengagement of the drive assembly gear teeth with the gear teeth of the floor surface treatment device.</p> |
