ABSTRACT:
This invention is a machine for washing vehicles. A plurality of horizontal and vertical rotating brushes are provided to move over a car's surface to scrub it. Horizontal top brushes are mounted on pivoting brush arms which are counterbalanced by springs to assure relatively constant brush pressure on a vehicle surface regardless of the brush arm's orientation. Additionally, generally vertical side brushes are stacked in tandem on each side of the machine to wash the sides of a vehicle. These tandem side brushes are supported by inwardly canted shafts enabling the brushes to freely fall against the sides of a vehicle. Each side brush is independently driven at its outermost end to allow independent control of each brush. Means for guiding a vehicle into the wash bay is also provided. This is preferably a vertical water beam disposed within the wash bay by which a driver can accurately position a vehicle for washing.
