Abstract

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 an outlet of 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 valve is provided in the outlet of said dispensing tank. The valve has a stem moveable between a closed position sealing the outlet and an open position providing fluid communication between the dispensing tank and the nozzle. A pin is mounted on the handle assembly and is adapted to open and close the valve by engaging the valve stem to move the stem to an open position when the dispensing tank is mounted on the handle assembly. A boot seal is preassembled with the pin and is mounted as a unit with the pin on the handle assembly to prevent leakage.
