Abstract
Abstract A public rest room is automatically washed, rinsed, sanitized and dried by nozzles strategically placed for directing appropriate fluids in sequential fashion over every area of the wall and floor surface of the room and into effective contact with the wash and toilet facilities in the room with the nozzles being supplied with wash, rinse, sanitizing and drying fluids from appropriate reservoirs and supplies through valved conduit means disposed along the walls of the room. The cleaning system may be installed in existing public rest rooms; in addition, the room may be a self-contained structure that may be placed adjacent an erected building or permanently installed in a building, such as a gasoline service station. The cleaning system contains the nozzle arrangement and attendant operating structure and components as a built-in adjunct to its operation and maintenance.
