Abstract
An open top, double walled, plastic hot water storage tank is mounted within a two section injected plastic casing and is spaced internally from the walls of the casing to thermally insulate the hot water tank. A removable cylindrical dump tank closely fits the interior of a cylindrical inner wall of the storage tank. A rotatable dome locks to the upper casing half to seal off the top of the dump tank. The dump tank bears a splash deflector and filter assembly when the machine functions as a wet vacuum extraction machine. A cloth filter bag and internally replaceable paper filter bag operate in place of the dump tank when the machine functions as a dry vacuum extraction machine. A water jet circulation bypass loop maintains the water in the hot water tank in circulation. Both the vacuum pump and water are double electrically insulated. A tool caddy clamps to the casing to permit the casing to stand on end for storage of the apparatus when not in use. The tool caddy carries removable tools for selective coupling to a conventional vacuum cleaner wand.
