Method of cleaning a pool with a robot

1) Method (200) for cleaning a pool (50) comprising a bottom (52) and N vertical walls (53, 54) by means of a robot (100) comprising a contact detector (104) and a chassis on which a set of left-hand wheels (104) and a set of right-hand wheels (106) are mounted, each set being rotated by a motor (108, 110) controlled by a control unit (112), the cleaning method (200) comprising:

• an adjustment step (202) during which the control unit (112) controls the motors (108, 110) in order to adjust the robot (100) against the vertical wall of rank n=1,
• an advancement step (204) during which the control unit (112) controls the motors (108, 110) in order to advance the robot (100) along the vertical wall of rank n until the vertical wall of rank n+1 is detected by the contact detector (114),
• a release step (206) during which the control unit (112) controls the motors (108, 110) in order to withdraw the robot (100) over a release distance in order to be released from the vertical wall of rank n+1,
• a rotation step (208) during which the control unit (112) controls the motors (108, 110) to make the robot (100) rotate on itself in order to be adjusted against the vertical wall of rank n+1,
• a test step (210) during which the control unit (112) checks whether n is equal to N,
• when n is different from N, the cleaning method (200) continues with:
• an incrementation step (212) during which the control unit (112) increments the value of n by “1”, and
• a looping (214) during which the cleaning method (200) loops onto the advancement step (204),
• when n is equal to N, the cleaning method (200) continues with:
• a finishing step (216) during which the control unit (112) controls the motors (108, 110) in order to advance the robot (100) along the vertical wall of rank “1” until the vertical wall of rank “2” is detected by the contact detector (114),
• a stop step (218).
