<p>An apparatus and process for impinging a fluid upon an object to be treated is described. A generally conical-shaped flow of fluid is directed from the cleaning device onto a surface. The fluid contacts the surface and then is reflected through an opening defined by the device and against a deflection plate. The deflection plate has a shape configured to direct the fluid into a fluid return and back onto the surface to be treated.</p> |
