According to the inventive method for controlling an automatic cleaning device used for cleaning the surface of a window, the cleaning head is first advanced onto the window surface, approximately in the center or close to the edge, by means of a powered control system. This starting position is determined using the basic information for the building concerned provided in the plans of the building. The cleaning head is subsequently moved over the window surface as far as the window frame in direction X or Z, in a first seek-edges-mode, then moved along the window frame into the corner of the window, where the actual cleaning process starts. The frame of the cleaning head can be moved elastically in relation to the fixed structure so that the control device is able to determine whether the cleaning head is in contact with a window edge. In the case of windows without frames, a sensor can be provided, the signal of the sensor being detected by the control device.

Selon un procédé permettant la commande d'un dispositif automatique de nettoyage utilisable notamment dans le cas du nettoyage de la surface d'une fenêtre, la tête de nettoyage est tout d'abord déplacée, par servocommande, sensiblement au milieu ou au voisinage du bord, à l'encontre de la surface de la fenêtre. Cette position de départ résulte des données fondamentales du bâtiment correspondant, sur la base du plan de construction. La tête de nettoyage est ensuite déplacée en direction X ou Y, en un premier mode de recherche des bords, au-dessus de la surface de la fenêtre, jusqu'au cadre de la fenêtre, puis le long du cadre, dans le coin correspondant de la fenêtre où commence le processus de nettoyage proprement dit. Le cadre de la tête de nettoyage est mobile élastiquement par rapport à la structure fixe, de sorte que le dispositif de commande est en mesure de détecter si la tête de nettoyage est en contact avec un bord de la fenêtre. En variante, on peut prévoir, pour les fenêtres sans cadre, un détecteur dont le signal est détecté par le dispositif de commande.
