Spray attachment for Electrolux vacuum cleaner. Glass jar threaded into red plastic body with perpendicular cylindrical air passageway. Vacuum hose nozzle fits into one end of cylinder. Vacuum hose is attached temporarily to the air discharge port on the vacuum cleaner. Passage of air through the cylindrical passageway causes liquid in the jar to be combined into the escaping air stream. There is a port on top of the unit which enables or disables the liquid flow by introducing a vacuum leak. This port is covered by the thumb to enable liquid flow. This device demonstrates the “venturi effect”.
