Abstract
To treat a surface by a device attracted to the surface by vacuum, it is necessary in most cases to guide a working device with a certain contact pressure over the surface. To be able to set the contact pressure of the working device with little effort, the device according to the invention rests at three points on the surface, one support point being formed by the working device. The force of attraction of the device against the surface is, therefore, accurately distributed to the working device and the other two supports so that the pressure force of the working device can be specifically varied and also controlled by varying the vacuum between the device and the surface.
