<p>The system has a deployment piston (110A) connected to a cleaner robot (100A) and moved in a pipe communicating with a swimming pool. A pressure device generates extra pressure in the pipe during a cleaning stage of the swimming pool so as to drive the deployment piston to a position in the pipe. A suction device generates suction in the pipe during a water filtering stage of the swimming pool when the robot is inactive so as to suck the deployment piston to another position in the pipe in order to permit a stowing process of the robot in the latter position.</p> |
