ABSTRACT:
A combined nozzle and cleaning fluid dispenser for a fluid vacuum cleaning system is provided. The combined nozzle and cleaning fluid dispenser is for simultaneously applying a cleaning fluid and a vacuum force to a surface or object. The combined nozzle and cleaning fluid dispenser includes a hollow, rigid wand attached to a suction chamber having an open, free end. Attached to the wand is a cleaning fluid sprayer which includes a valve, a lever arm and a spray head for dispensing a cleaning fluid. In accordance with the present invention, the spray head is positioned within the suction chamber. In this arrangement, the cleaning fluid is substantially prevented from being dispensed from the suction chamber unless the suction chamber is in contact with a surface to be cleaned. The combined nozzle and cleaning fluid dispenser of the present invention not only prevents against pooling or puddling of the cleaning fluid but also allows for controlled and precise dispensation of the fluid.
