ABSTRACT:
The use of liquid aspirators which are connected to conventional vacuum cleaners is known. In this invention the body exists of two separate body parts which are held together by a filter cartridge. The said rear body piece is provided with an extended tube in which a hose from a conventional vacuum cleaner inserts. Also said rear body piece holds a cartridge containing a filter and filter support where liquid is filtered through. The front said body piece acts as the liquid reservoir and is provided with a tube connected to the front nozzle of said body part extending along the top of said body part and protruding through the filter cartridge to the back of rear body part. The liquid aspirated by suction of vacuum cleaner is discharged to the rear of assembled unit. The filter cartridge slows air and water speed down and distributes liquid to front liquid reservoir, where at a predetermined level floats are activated to cut off air flow, thus stopping liquid flow before penetrating hose of vacuum cleaner preventing moisture damage. Front and rear said body parts may be separated easily to empty apparatus thus resetting floats enabling the apparatus to perform again.
