ABSTRACT:
A scrubber for an automotive vehicle. The scrubber includes a brush, pivot and centering assembly. The brush scrubs the vehicle. The pivot allows the brush to change angular orientation. The centering means urges the brush toward a single predetermined angular orientation. In this way, should a vehicle drive into the brush, the brush may pivot with the force applied to it, reducing the chance that the brush or the vehicle will be damaged. The centering mechanism, however, urges the brush toward a predetermined angular orientation so that, absent an external force applied to the brush, the brush will be in a predetermined position ready for scrubbing the vehicle.
