PROBLEM TO BE SOLVED: To provide a device for cleaning or processing a surface and a method for operating the device.SOLUTION: A device for cleaning or processing a surface, includes a light source (3) for illuminating the surface (2) with light and an optical detection unit (4) for detecting the light reflected by the surface (2). 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 unit (4) has at least one filter element (5) and at least one sensor element (6), which are arranged and designed to detect the light reflected from the surface (2) with respect to at least four different spectral ranges. |
