ABSTRACT:
The invention relates to a process and apparatus for cleaning a swimming pool, where the apparatus or device, moves back and forth in the swimming pool, and where the device has driving gears or belts that can be switched to drive reverse or forward during operation. A contact rail is frontally positioned in the cleaning casing of the device, and a swich rail is positioned at the rear of the casing. Correction-dependent signals are obtained by the device striking an obstacle and these signals are supplied to a gear via a control mechanism. Upon obtaining such signals, the driving gear or belt slows down and remains still for so long until the other driving gear or belt which is still moving turns the cleaning device around and until the rear switch rail is activated. The signals resulting from the switch rail are used for switching the gear to reverse and for straightening out the cleaning device to a new position and prepare it to a forwards motion to continue its course along the swimming pool.
