Abstract
A mobile machine for cleaning swimming pools by suction removal of sediment from the bottom of the swimming pools comprises a water turbine driving a drive wheel in such a way that the machine follows a self-steered path on the bottom of the swimming pools. The drive wheel is capable of rotating about a vertical steering axle to prevent the machine from becoming blocked at a wall or in a corner of the swimming pools.
