Patent ID: 7627926

Claim:
A cleaning apparatus, comprising: a housing which is moveable across a supporting surface; a first electrically actuated fluid pump which is mounted in the housing, and which is operable to deliver a first stream of fluid at a pressure of at least about 150 PSI to less than about 1200 PSI; a second electrically actuated fluid pump, discrete and different from the first electrically actuated pump, which is mounted in the housing, and which is operable to deliver a second stream of fluid, at a pressure, of less than about 150 PSI; an electrically actuated heater which is mounted in the housing, and which is operable to impart heat energy to the second fluid stream; an electrically actuated vacuum pump which is mounted in the housing; wherein the first and second electrically actuated pumps, when individually energized, are operable to deliver the first and second streams of fluid onto a surface to be cleaned and wherein the electrically actuated vacuum pump is operable to recover the fluid which has been previously deposited onto the surface to be cleaned; and wherein the first electrically actuated pump is energized from a first AC power source and the second electrically actuated pump is energized from a second AC power source discrete and different from the first AC power source.
