The invention relates to a device (1), in particular a cleaning robot, for treating a surface (2). The device (1) has an optical measuring device (3) for detecting the surface (2) type. The aim of the invention is to provide a surface treating device comprising an optical measuring device for detecting the surface type, said measuring device allowing a reliable detection of the surface type with little technical complexity. This is achieved in that the optical measuring device (3) has a light source (4) and at least two light sensors (5, 6), and the light source (4) and a first light sensor (5) are arranged such that light emitted from the light source (4) strikes a reflection point (7) of the surface (2) at an angle of incidence (α) and is subsequently reflected to the first light sensor (5) at a corresponding angle of reflection (β). The light source (4), the reflection point (7), and the first light sensor (5) define a plane of incidence (8), and a secondary plane (9) which intersects the reflection point (7) and has a second light sensor (6) is defined perpendicularly to the surface (2), said secondary plane forming an angle (δ) between 80° and 100° relative to the plane of incidence (8). A straight line which runs through the reflection point (7) and the second light sensor (6) forms an angle (γ) relative to the surface (2), said angle being substantially as large as the angle of incidence (α) or the angle of reflection (β). |
