Submersible vacuum cleaner
First Claim
Patent Images
1. A submersible vacuum for cleaning surfaces submerged in a liquid comprising:
- an elongated substantially rigid handle having an operating end and an opposite end,a submersible container coupled substantially rigidly to the opposite end of the handle substantially coaxially therewith at one end of the container and defining a sealed motor chamber and a filter chamber, the container further defining a liquid inlet port to the filter chamber at an opposite end of the container substantially coaxially therewith, the container also defining a liquid discharge opening from the filter chamber to the exterior of the container;
a liquid seal separating the motor chamber from the filter chamber;
a pump impeller and a filter mounted in the filter chamber, the pump impeller and the filter being disposed relative to the inlet port and the discharge opening for flow of liquid through the inlet port, the filter, and the discharge opening in response to the operation of the impeller;
an electric motor mounted in the motor chamber, the motor having a motor shaft extending through the liquid seal to the filter chamber and mounting the impeller thereto;
means for supplying power to the motor enclosed in the motor chamber, andmeans for coupling to the inlet port for support and carriage by the container an inlet device cooperable with a surface to be cleaned and defined for flow of liquid therethrough to the inlet port.

Abstract
The invention provides a self-contained cordless electric pool and spa vacuum cleaner which is easily maneuverable over both flat and highly contoured underwater surfaces. A pump impeller, powered by an electric motor, is used to draw water through a compact filter cartridge. The efficiency of the filter cartridge allows for the use of a small motor and small battery which, in turn, result in the small size of the vacuum cleaner. All electrical components are enclosed in a watertight chamber so as to allow the entire cleaner to be submerged under water.
