First Claim
Patent Images
1. A wet/dry vacuum cleaner for cleaning debris from a surface wetted with liquid material comprising:
- a tank having an inlet for receiving the liquid material and an outlet for disposing the liquid material;
an air impeller housing having an opening in air flow communication with the tank interior;
an air impeller disposed inside the air impeller housing to create low pressure in the tank;
a motor disposed inside a motor housing and operatively coupled to the air impeller;
an inlet hose removably connected to the inlet;
a nozzle removably attached to the inlet hose and adapted to engage the surface for dislodging the debris from the surface, the debris and liquid material being passed through the inlet hose; and
a filter disposed in the inlet hose and adapted to remove debris from the liquid material;
wherein the nozzle dislodges debris from the surface, and the debris and the liquid material are pulled through the inlet hose.

Abstract
A vacuum cleaner for cleaning ponds or swimming pools includes a tank for holding debris and liquid material. Liquid material is filtered prior to being drawn into the tank, to then be pumped out of the tank. Alternately, liquid material is drawn into the tank and is filtered when being pumped out of the tank. A metering device may be provided for restricting flow into the tank, thereby allowing the vacuum cleaner to be operated continuously.
