Abstract: The invention relates to a method for cleaning a floor surface with a floor cleaning device, in which method, during the cleaning movement of the floor cleaning device over the floor surface, a first recording of a floor surface portion before the cleaning is created with an optical recording unit, the floor cleaning device is moved with at least one cleaning unit over the floor surface portion, which is cleaned, a second recording of the floor surface portion after the cleaning is created with an optical recording unit and the recordings are compared with one another in order to check the cleaning result. The invention further relates to a floor cleaning device for carrying out the method.

Abstract: A method for treating a floor surface is provided using a self-propelled and self-steering floor treating apparatus, wherein the treatment is based on a pattern along which the floor treating apparatus is moved, wherein the pattern has paths in side-by-side relationship to one another, and wherein when the floor treating apparatus travels a path, a respective treatment area is covered and treated. The pattern is adapted to at least one of the size and contour of the floor surface such that boundaries thereof opposite each other each have a path extending therealong with a treatment area adjacent to the boundary and intermediate paths are arranged such that full-coverage treatment of the floor surface is realized, wherein the relative position of at least two paths in side-by-side relationship is such that the treatment areas thereof at least partially overlap. A floor treatment apparatus for carrying out the method is also provided.
