ABSTRACT:
A method for washing a vehicle is disclosed in which a brush assembly, which includes a brush, a brush shaft supporting the brush, a brush motor for driving the brush shaft and a flexible coupling, is permitted to swing or tilt in response to the force exerted on the brush by the movement of the vehicle relative to the vehicle washing apparatus. The flexing of the flexible coupling, which couples the brush shaft to the support arm, permits the brush to tilt or swing in any direction. The brush motor rotates the brush in a direction which causes the brush to walk along the front of the vehicle. As a result, the cooperative action of the rotary reaction force of the brush and the flex of the flexible coupling causes the brush to turn the front corner of the vehicle and pass along the side of the vehicle. Similarly, the flex of the flexible coupling together with the rotary reaction force of the brush against the vehicle enables the brush to wash the side and turn the rear corner to wash the rear of the vehicle.
