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