Patent ID: 8595880

Claim:
Rolling apparatus for cleaning an immersed surface comprising: a body configured so as to be movable over the immersed surface at least in one direction of advance and in a main orientation of advance, called a longitudinal orientation, rolling members which have contact zones with the immersed surface defining a rolling plane of the body over the immersed surface, a filtration chamber which is provided in the hollow body and which has: at least one liquid inlet into the body, at least one liquid outlet out of the body, at least one hydraulic circuit for circulation of liquid between at least one liquid inlet and at least one liquid outlet through at least one filtering device, at least one motorized pumping device which is at least partially interposed in a hydraulic circuit and configured for producing a flow of liquid between each liquid inlet and each liquid outlet connected by said hydraulic circuit, wherein it comprises: a flux guide which is mounted on a liquid outlet, called a propulsion outlet, said flux guide comprising at least one movable deflection member and having a shape arranged for orientating a current of liquid which is discharged via said propulsion outlet through said flux guide so as to create, by means of reaction, at an outlet of the flux guide, forces whose resultant, called a hydraulic reaction force, has a non-zero drive component of the apparatus, called a horizontal component, parallel with said rolling plane, an actuator for driving said at least one movable deflection member of said flux guide, said actuator being configured for orientating and retaining said at least one movable deflection member in at least two different positions corresponding to two horizontal components having different orientations, configured for driving the apparatus in at least two different orientations, at least one of which corresponds to the longitudinal orientation and the other is different both from the longitudinal orientation and the direction opposite the longitudinal orientation, a unit for automatically controlling said actuator.
