Abstract
Abstract A vehicle washing apparatus including frame-mounted overhead rotary brush assembly which can scrub the vehicle surface with a continuously applied optimum amount of scrubbing pressure, and which is caused to ascend and descend in increments as small or as large as required while the frame travels horizontally on its track, so that a vehicle can be automatically washed from front to back via the hood, roof and trunk portions.
