ABSTRACT:
A portable scrubbing device (10) includes a support base (12) for placement on a generally horizontal surface, a motor (14) including a rotatable shaft (16) and mounted to the support base (12) so that the rotatable shaft (16) extends upwardly at an angle from the support base (12), and a brush (18) attached to the shaft (16) for rotation with the shaft (16). The shaft (16) includes a portion having a non-circular cross-section, and the brush (18) includes a sleeve (36) having a portion with a corresponding non-circular cross-section that mates with the shaft (16). The angle at which the shaft (16) is mounted relative to support base (12) and the shape of the shaft (16) and the sleeve (36) cooperate to hold the brush (18) on the shaft (16) and to rotate the brush (18) with the shaft (16) without the use of additional fasteners such as set screws or threaded fittings.
