Abstract

A method for operating a floor processing device that moves automatically within an environment, has a detection system of the floor processing device that detects features of a surface to be cleaned and compares them with reference features of carpets. Upon detection of a carpet, it is determined whether and where the carpet has fringes, and the fringes are aligned in a defined direction relative to the carpet by means of a combing attachment of the floor processing device.
