Abstract
A hydraulically driven rotary brush for cleaning vehicles and the like. This is a rotary brush system wherein the brush rotates about an axis parallel to the item being washed. It has a wand for the attachment to a source of water at one end, and a brush mounted at the further end. Water flowing through the wand is diverted into a channel or channels for the operation of at least one turbine unit connected to the drum supporting the brush. Water exiting from the turbine unit is directed onto the surface being washed to thoroughly flush the same. The drum is provided with means for inserting detergents and/or waxes within the drum, and apertures are provided within the surface of the drum whereby these materials can be fed to the brush whereupon they mix with the water for application to the surface. Provision is made whereby the drum can be readily removed, for example, for the replacement of the bristles or elements of the brush itself.
