The invention relates to a device (1) for treating a surface (21), in particular to a cleaning robot, having a detection device (2) for identifying the type of surface (21), which detection device (2) has a light source (3, 4, 5, 6) for irradiating the surface (21) with light and has a sensor (7) for detecting the light which is reflected by the surface (21). In order to improve the identification of the type of surface, it is proposed that a three-dimensional screen panel (12) which forms a plurality of partial volumes (13, 14, 15, 16) is associated with the sensor (7), wherein each partial volume (13, 14, 15, 16) is in each case associated with a different sensor subarea (8, 9, 10, 11) of the sensor (7), and wherein adjacent sensor subareas (8, 9, 10, 11) are optically separated from one another by means of the screen panel (12) such that light is prevented from passing from a first partial volume (13, 14, 15, 16) to a second partial volume (13, 14, 15, 16). Furthermore, the invention relates to a method for operating a device (1) for treating a surface (21). |
