Abstract (en)
[origin: WO9800239A2] A cyclonic power wash system including a roving sprayer and retrieval unit that uses high pressure, high temperature water for selectively cleaning large, flat, concrete or asphalt surfaces and can retrieve a substantial portion of the dispensed water along with the matter picked up from the surfaces. The sprayed water is reclaimed by the retrieval rotor that is power driven. The roving sprayer and retrieval unit can function as a stand alone unit or in combination with a component carrying platform that includes a reclamation tank in which the retrived water and matter is processed and separated so that the separated water can be reused by the roving sprayer and retrieval unit. A rotary union in the roving sprayer and retrieval unit, prevents water, passing from the inlet of the rotary union to the discharge thereof, from leaking through or around a seal that is formed by pressing together a pair of hard, durable sealing surfaces. The invention can also be used as a liquid pick up device for example to pick up the deicing fluid that falls to the surface when spraying an aircraft to prevent icing.
