Abstract
A device for cleaning or processing a surface, wherein the device has a light source for illuminating the surface with light and an optical detection device for detecting the light reflected by the surface. In addition, the invention relates to a method for operating a device according to the invention. To create a device for cleaning or processing a surface and a method of the type in question, which differentiates various surfaces with a better resolution than that in the prior art, it is proposed that the optical detection device has at least one filter element and at least one sensor element, which are arranged and designed to detect the light reflected from the surface with respect to at least four different spectral ranges.
