This invention relates to a vehicle foam-washing apparatus including a double bag pneumatic pump, a mixing device, a heating device, a device for supplying water and detergent and a pipe for supplying high pressure gas, wherein the double bag pneumatic pump is driven by high pressure gas to continuously draw a given amount of water and detergent and to mix them with each other. The resulting mixture is foamed by passing through a filter mesh and is sprayed out onto the surface of the vehicle for the purpose of cleaning the same after the foam is increased and densified under the action of high pressure gas. Alternatively, the water and the detergent may be mixed beforehand or connected with pipes respectively, and the water may be heated in advance. |
