Abstract: A device for cleaning immersed surfaces comprising a supporting structure rrying rotary circular brushes for cleaning the surface and wheels for moving the device on the surface. When rotated the brushes produce a force of attraction towards the surface. Transmission means, for example, calibrated springs, transmit to the wheel a predetermined part of the force of attraction so that the force with which the brushes are pressed against the surface is diminished and the adhesion of the wheels to the surface is ensured.
