ABSTRACT:
An apparatus to clean or depollute surfaces or layers of water. The apparatus has at least one channel (12) which withdraws a stream of water at the front of the apparatus and discharges the water at the rear of the apparatus after cleaning or depollution. The water can be discharged through two conduits or tunnels (18), which diverge relative to each other. The flow of the stream of water through the channel (12) is caused by at least one propellor (20) driven by a motor which can be hydraulic.
