Pool cleaning robot
First Claim
1. A pool cleaning robot having means for suctioning debris from the bottom of the pool and a propulsion nozzle adapted for directing a propulsive jet of water in a direction opposite to a direction of movement of the robot, wherein the nozzle is rotationally mounted on an axis perpendicular to the plane of movement of the robot, in that the robot has means of stopping the rotation of the nozzle in at least two essentially opposite directions and means of controlling the stopping means, equipped so as to be operated by a hydrodynamic force created by the movement of the robot, wherein said robot has at least one wall, which disrupts the propulsion jet, on at least one part of an ejection perimeter of the nozzle, said wall constituting a part of a tipping cover, at least two openings for free passage of the jet being constructed in the cover.

Abstract
The subject of the invention is a pool cleaning robot having a structure for suctioning debris from the bottom of the pool and a propulsion nozzle (5) adapted for directing a propulsive jet of water in a direction opposite to a direction (D1,D2) of movement of the robot, characterized in that the nozzle (5) is rotatably mounted on an axis (z,z′) perpendicular to a plane of movement of the robot, in that the robot has a structure (12,13) for stopping the rotation of the nozzle in at least two essentially opposite directions and structure for controlling (7,71,72) the structure for stopping, equipped so as to be operated by a hydrodynamic force crated by the movement of the robot.
