An overhead frame supports a gear housing which supports a strip support frame from which flexible cleaning strips are hung. A motor driving a main shaft to which the housing is connected moves the strip support frame in a circular path about a first axis over the top of a vehicle while the strips contact the body of the vehicle for the scrubbing action. As the strip support frame is moved in the circular path, it is positively moved about a second axis parallel to the first and in a direction opposite the direction of movement in the path. The strip frame is rotatably mounted on an inclined portion of a second shaft whose main portion is on the second axis, so the strip support frame is rotatable on a third axis which is inclined with respect to the first and second axes. Rotation of the shaft having the inclined portion is provided by a gear coupling to a stationary gear in the rotating housing. Therefore, as the main shaft is rotated to provide the movement of the support frame in a circular path, the second shaft is rotated in an opposite direction and, with the support frame on an inclined portion of that shaft, a resulting positive vertical action of the scrubbing strips is achieved.
