Patent number: 10338595Abstract: 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.Type: GrantFiled: February 3, 2017Date of Patent: July 2, 2019Assignee: Alfred Kärcher SE & Co. KGInventors: Heiko Hoennige, Christian Hofner, Carsten Eckart
