Abstract: A robotic vacuum cleaner including a control system and a suction nozzle with a cleaning brush. The control system controls at least one of frequency and intensity of contact between the cleaning brush and each brushable portion of a floor surface to be cleaned such that at least one of the frequency and the intensity of contact between the cleaning brush and the floor surface decreases with a decrease of the distance to the at least one boundary of the floor surface.

Abstract: A robotic vacuum cleaner has a control system arranged for controlling at least frequency or intensity of contact between a cleaning brush of its suction nozzle (3) and each brushable portion of a floor surface (20) to be cleaned, such that, at least for some brushable portions of floor surface (20) closely adjacent to at least one of the boundaries (18) of the vacuum cleanable floor surface, at least the frequency or the intensity of contact between the cleaning brush and each of the floor surface portions decreases with a decrease of the distance to the at least one boundary of the vacuum cleanable floor surface (20). A method for robotic vacuum cleaning is also described. With the vacuum cleaner and the method of robotic vacuum cleaning according to the present invention the negative influence of vacuum cleaning on the durability of the visual attractiveness of a floor cover or a carpet is reduced.
