Patent ID: 8402586

Claim:
A motorized robot ( 1 ) for cleaning swimming pools or the like which operates submerged in a fluid, comprising: displacement means ( 2 ) for the robot, of the wheel, brush, or caterpillar type, comprising a surface ( 3 ) of contact with a submerged surface of displacement of said swimming pool or the like, means ( 4 ) for generating, through the robot, a circulation of the fluid in which the robot is submerged, comprising: an aspiration opening ( 5 ) for said fluid, a discharge opening ( 6 ) for the aspirated fluid, a fluid conduit ( 7 ) linking the aspiration and discharge openings, means ( 8 ) generating a stream of said fluid in said conduit, a strut ( 9 ) for lifting from the displacement surface, at least one part of said surface ( 3 ) of contact of the displacement means, said strut being movable at least between the following two positions: a first position, termed the inactive position, in which said strut is retracted inside the robot, said surface ( 3 ) of contact of the displacement means then being able to be entirely in contact with said displacement surface, a second position, termed the active position, in which said strut stands proud of said surface ( 3 ) of contact of the displacement means, so that a part of this surface ( 3 ) of contact can no longer be in contact with the displacement surface, characterized in that said robot furthermore comprises means ( 10 ) for controlling the displacement of said strut which are activated by a motion of the fluid in said fluid conduit, said means ( 10 ) for controlling the displacement of said strut ( 9 ) between active and inactive positions comprising means ( 11 ) for opposing the motion of the fluid in the fluid conduit ( 7 ), which are movable in the fluid conduit ( 7 ) so as to at least partially obstruct said conduit or to clear the fluid conduit ( 7 ), and are tied to the strut, in such a way that, depending on the position adopted in the fluid conduit by said opposing means, the strut takes an active or inactive position.
