摘要: A low-cost accessory for a conventional tank-type wet-pickup vacuum cleaner which converts such into self-contained hot water extraction type of carpet shampooer and floor suitable use by homeowners. The includes reservoir attaches compactly to the cleaner. is intended be filled with cleaning solution detergent means feeding spray nozzle located behind pickup nozzle. hand-controlled valve permits operator dispense interrupt flow while vacuuming wetted or carpet. In preferred embodiment pressurizable toroidal shaped tank fits around pressurized an integral manual air pump. An indicating pressure relief provides measure prevents over pressurization reservoir. forces modified embodiment, motor driven pump assembly employed deliver fluid point thus, eliminating need
