Patent ID: 7188632

Claim:
A cleaning and sanitizing system, comprising: a first discharge nozzle; a first conduit for delivering water to the first discharge nozzle to be discharged by the first discharge nozzle as a first stream; a second discharge nozzle; a second conduit for delivering ozone/water to the second discharge nozzle, to be discharged from the second discharge nozzle as a stream of ozone/water; a source of water connected to the first conduit for delivering ozone/water into and through the first conduit and out from the first discharge nozzle as a stream of high pressure water; a source of ozone/water connected to the second conduit for delivering ozone/water into and through the second conduit and out from the second discharge nozzle as a stream of ozone/water; said first and second nozzles being positioned relative to each other so that the water and ozone/water streams are contiguous but the ozone is not delivered into the high pressure water stream, and; wherein the high pressure water stream is discharged at a pressure that exerts a cleaning force on a surface to be cleaned and ; and wherein the second discharge nozzle concentrically surrounds the first discharge nozzle and wherein the system is configured to discharge an ozone/water stream that concentrically surrounds a high pressure water stream that is discharged from the first nozzle.
