Abstract

A floor processing device automatically moves within an environment, with a driving attachment, a floor processing unit, an obstacle detection unit, a control unit and a detection unit for detecting device parameters and/or environment parameters control unit is set up to determine an error of the floor processing device based upon the detected parameters that prevents the floor processing device from moving and/or the floor processing device from processing a surface to be processed in such a way that the floor processing device is unable to automatically extricate itself from the error situation. The control unite is set up to analyze the parameters detected by the detection unit with respect to recurring patterns that have a repeatedly encountered combination of an error and at least one chronologically preceding environment and/or device parameter.
