An upright wet extractor includes a base assembly, a manipulative handle pivotally attached to the base assembly, and a motor driven agitator brush. A cleaning solution dispensing tank is removably attached to the handle assembly by a pivotable latch member. In a floor cleaning mode, cleaning solution is selectively supplied by gravity from the dispensing tank to a floor cleaning spray nozzle through a supply tube which is controlled by a pinch valve. In an attachment hose cleaning mode, cleaning solution is selectively supplied by a motor driven pump from the dispensing tank to an attachment hose spray nozzle which is controlled by a trigger valve. A suction motor/fan assembly is carried by the base assembly which is selectively in fluid communication with a floor suction nozzle in the floor cleaning mode and an attachment hose suction nozzle when in the attachment hose cleaning mode. Conversion between the floor cleaning mode and the attachment hose cleaning mode is conveniently carried out by manual operation of a knob of multi-functional valve/switch assembly. The valve/switch assembly includes a valve member which diverts the flow of working air and a micro-switch which appropriately activates and deactivates the agitator brush motor and the pump motor. A recovery tank assembly which both separates liquid from air and stores the recovered liquid is removably secured within the base assembly below the suction pump and can be removed through the rear end of the base assembly. The suction motor/fan assembly includes a cooling fan which draws cooling air over both the pump motor and the motor of the suction motor/fan assembly.
