    摘要： An improved cleaning system of the type which applies a cleaning fluid to a surface to be cleaned and then vacuums the dirty cleaning fluid from said surface is provided. The system includes a cleaning fluid pump for delivering pressurized cleaning fluid to spray nozzles attached to either a floor nozzle or a hand tool. Both the floor nozzle and the hand tool are connected to the suction and cleaning fluid connectors of the main cleaner unit by a one-step connection which connects both fluid and suction lines in a single motion. The hand tool, which is attached to the main unit by a hose assembly, has its own pinch valve for controlling the application of cleaning fluid to the surface to be cleaned. When the hand tool is being used the trigger which actuates the pump may be locked in the "on" position.
