For treating a surface (1) by means of a device (2) that is drawn to the surface by negative pressure it is usually necessary to guide a treatment device across the surface (1) at a defined load pressure. The aim of the invention is to provide a device with which the load pressure of the treatment device (6) can be adjusted with little technical effort. To this end, the device (2) rests on the surface (1) via three points, one point of support being the treatment device (6). This arrangement allows for an exact distribution of the attraction of the device (2) towards the surface (1) to the treatment device (6) and the other two supports (8) so that the load pressure of the treatment device (6) can be specifically modified and regulated by changing the negative pressure between the device (2) and the surface (1).

Pour permettre de traiter une surface (1) au moyen d'un dispositif (2) attirant à lui la surface par dépression, il est dans la plupart des cas nécessaire d'amener un dispositif de traitement sur la surface (1) avec une pression d'appui déterminée. Afin de pouvoir régler la pression d'appui du dispositif de traitement (6) sans que cela s'avère trop coûteux, le dispositif (2) repose sur la surface (1) par l'intermédiaire de trois points, l'un des points d'appui étant formé par le dispositif de traitement (6). Cela permet d'obtenir une répartition précise de la force d'attraction du dispositif (2) contre la surface (1) sur le dispositif de traitement (6) et les deux autres points d'appui (8), de sorte que la force d'appui du dispositif de traitement (6) peut être modifiée de manière ciblée par modification de la dépression entre le dispositif (2) et la surface (1) et peut également être réglée.
