Abstract

An electric-powered submersible vacuum cleaner for filtering water in a pool includes a base with an inlet port extending therethrough. A plurality of wheels extends from the lower surface of the base to facilitate movement of the cleaner over a surface of the pool. An impeller coaxially aligned with the inlet draws water and debris from the pool surface. An electric-powered drive train is coupled to the cleaner and configured to rotate the impeller. A discharge conduit in fluid communication with the inlet extends substantially normal with respect to the upper surface of the base and circumscribes the impeller to direct the flow of water/debris drawn through the inlet by the impeller. A filter mounted over the discharge conduit filters the debris from the drawn water and passes filtered water into the pool. A rotatable handle is attached to and facilitates manual movement of the cleaner over the pool surface.

Dependent claims

An electric-powered submersible vacuum cleaner for filtering water in a pool comprising:

a submersible housing having a base, a discharge conduit, and an outwardly extending flange, the base including an upper surface and a lower surface, the lower surface being positionable over a surface of the pool to be cleaned, and at least one opening extending through the upper and lower surfaces to define an inlet port;
a plurality of rotationally-mounted supports extending from the lower surface of the base and configured to facilitate movement of the vacuum cleaner over the surface of the pool;
an impeller coaxially aligned with the inlet port of the base for drawing said water and debris from the surface of the pool;
an electric-powered drive train directly coupled above the and configured to rotate the impeller;
the discharge conduit having an upper portion and a lower portion, the lower portion being in fluid communication with the inlet port and extending substantially normal from the upper surface of the base, said discharge conduit circumscribing at least a portion of the impeller to direct the flow of water and debris drawn through the inlet by the impeller;
a filter mounted to receive the water from over the discharge conduit and configured to filter the debris from the drawn water and pass filtered water into the pool;
the outwardly extending flange extending from the upper portion of the discharge conduit and configured to secure the filter to the housing, wherein the impeller includes a plurality of blades having a leading edge and a trailing edge, the impeller being set at a height such that the leading edges of the impeller blades are positioned to extend into the discharge conduit below a lower portion of the outwardly extending flange and the trailing edges of the impeller blades extend above the lower portion of the outwardly extending flange;
and
a handle configured to attach to and facilitate manual movement of the vacuum cleaner housing over the surface of the pool.

a filter mounted to the housing over an outlet of the discharge conduit and configured to filter the debris from the drawn water and pass filtered water into the pool;
and
a handle configured to attach to and facilitate manual movement of the vacuum cleaner over the surface of the pool.
