<p>A device for treating an operating area on a wall, comprising a working head (1), at least two cable holders (2) extending in front of the operating area, and, for each cable, an actuator (3) for setting the length of the supporting cable (2) obliquely linking the working head (1) to the cable holder. Actuating the actuators to set the length of the supporting cables enables the working head to be moved about in front of the operating area.</p> |
