ABSTRACT:
This portable carwash apparatus includes a mobile body carrying a brush support assembly having a forwardly projecting boom carrying the brush, a rearwardly projecting handle and a post, pivotally mounted to the body for swinging movement of the boom and brush by means of the handle between operating positions on either side of the body. A brush drive assembly is mounted to the brush support assembly so that the two assemblies can be lifted from the body as a unit. The body houses a reservoir and a rearwardly disposed power pack and includes spray nozzles on each side for selectively directing cleaning liquid pumped from the reservoir onto the brush. An automatic switching mechanism is provided for the brush drive assembly and pumping assembly so that the brush rotation and spray direction are changed when the brush is moved from one operating position to the other.
