ABSTRACT:
The surface cleaning apparatus is provided in self-propelled embodiments and in a trailer embodiment. The apparatus draws liquid from a supplied tank. Liquid is pressurized to approximately 4,000 psi, then directly to the surface to be cleaned. All cleaning and cleaning component functions are powered via the same fluid pumps via a supply manifold. Total width limitations dictated the design of the sidewalk capable apparatus.
