Abstract: The present invention is a novel design for a recirculating vacuum cleaner nozzle that addresses the problem of pluming by venting some internal fluid to the atmosphere. The nozzle guides fluid flow around an inner shroud within a housing. The distal end of the nozzle is exposed to the atmosphere such that air passes rapidly across its face from the outside edges to the inner duct. This rapidly moving airflow picks up dust and debris and carries it to the interior of the inner duct. Dusty air within this duct is preferably cleaned with a separator. After the fluid is cleaned, it may be sent back to the nozzle to pick up more debris. Use of the nozzle of the present invention in conjunction with a separator allows sufficient air to enter the nozzle to prevent pluming and allows the same amount of air to exit via shaped vent holes while retaining dust in the system.

The shroud may take alternative forms, including pairs of wings disposed on opposite sides of the primary discharge orifice or hollow structures that surround the airknife housing. The airknife further is adapted for low pressure direction and application of air laden particles, such as preatomized liquid particles.

Abstract: 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.
