Abstract
The invention relates to a self-propelled floor treatment device (), in particular to a cleaning robot, with a floor treatment element (), at least two motorized wheels () and a detection device for detecting a floor type of a surface to be treated. In order to easily achieve an optimal detection of the floor type, it is proposed that the detection device have a frictional resistance element (), which contacts the surface during a movement in such a way that a resultant force outside of a reference axis () acts on the floor treatment device (), wherein the reference axis () is oriented parallel to a main direction of movement () of the floor treatment device () prescribed by the orientation of the wheels (), and is aligned centrally between the wheels () in relation to a direction perpendicular to the reference axis (). Further proposed is a method for operating a self-propelled floor treatment device ().
