A self-propelled, self-steering floor cleaner is provided, including a cleaning device with at least one cleaning unit for cleaning a floor surface of a room having at least a section of an obstacle therein that is not in contact with the floor surface, a transmission unit for emitting radiation directed at the obstacle and the floor surface, a detection unit for detecting reflected radiation and providing a detection signal, a control unit coupled to the detection unit, and a chassis for movement on the floor surface including a drive unit coupled to the control unit, it being determinable from the detection signal whether a space and a cleanable floor surface section are present underneath the obstacle, the drive unit being actuatable to move the floor cleaner for cleaning the floor surface section, with at least one cleaning unit. The invention also relates to a method for cleaning a floor surface.

Self-propelled and self-steering floor cleaner and method for cleaning a floor surface

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.
