Abstract
A fluid circuit for a cleaning device having a mixture with separate water and cleaning fluid inlets and fittings interconnecting a pressurized source of water and a pressurized source of cleaning fluid responsive to change the mixing ratio of cleaning fluid to water as well as to assure the degree of mixing. The outlet of the mixing device is provided to a spray nozzle wherein the mixed fluid is projected onto a cleaning surface by an air stream through the spray nozzle. A common pump provides two levels of air pressure, a high one to the spray nozzle and a lower one to the pressurized sources of water and cleaning fluid.
