Cleaner device for swimming pools and the like
First Claim
1. A hydraulic cleaner device for a swimming pool and the like in which a water pump is provided for drawing water from the pool through a tube, said cleaner device comprising a casing having an open bottom, a shaft carried by said casing, a set of spaced wheels mounted on said shaft for supporting said casing on the bottom of a pool, brushes provided between said wheels for sweeping material from the bottom of the pool into the open bottom of the casing as said cleaner device moves along the bottom of the pool, an axial turbine having a rotor, a reducing and transmitting mechanism between said rotor and said shaft, the interior of said casing being divided into two compartments by a partition wall delimiting a water inlet to said axial turbine, a first one of said two compartments in said casing being positioned downstream of said axial turbine and being adapted to be connected to said tube, rotation of said rotor due to the flow of water through said axial turbine driving said shaft through said reducing and transmitting mechanism to rotate said wheels thereby to effect movement of said cleaner device along the bottom of the pool, a buoyancy member connected to said casing for maintaining said casing in a substantially vertical position on the bottom of the pool when said cleaner device is immersed in the pool.

Abstract
A hydraulic cleaner device comprises a water pump for drawing water from a pool through a tube, an open bottom casing divided into two compartments by a partition wall delimiting an inlet for an axial turbine having a rotor that drives a shaft connected by a reducing and transmitting mechanism to a set of wheels supporting the casing and a brush sweeping unit for movement along the bottom of the pool. One of the compartments of the casing is placed downstream of the axial turbine and is connected to the tube leading to the pump. An immersed buoyancy member is connected to the casing.
