An inlet hose feeds a tank that may be placed in a household sink which is too high above a floor for a conventional wet vacuum to lift a column of water. One or more inlet hoses each have a water pickup tube at the distal end. The hoses are connected to the tank chamber which has a vacuum created by a vacuum cleaner apparatus. An air inlet aperture in the pickup tube at the distal end of the inlet hose is kept above the water level. An air stream is drawn into the aperture of the pickup tube by the vacuum, which causes turbulence in the water stream in the pick up tube and breaks the water into droplets. This enables the vacuum of a given magnitude to lift the droplets to a higher elevation than a solid water column. Air inlet and water discharge valves are provided on the tank to control the water fill rate into the tank. An interior hose or channel stops the vacuum to the pickup hose when the fluid in the tank gets too high. A window in the tank permits observation of the fill rate. The valves are arranged to provide optimum water fill and discharge rates.
