ABSTRACT:
A robotic cleaning device having a main body with a controllable drive device to move the device over a surface, a cleaning device to clean the surface, an obstacle detecting device, and a control device connected to the drive device and the obstacle detecting device. The main body has a left wall connecting a front end portion with a left rear end portion and a right wall connecting the front end portion with a right rear end portion. The control device receives information from the obstacle detecting device about a detected obstacle and controls the drive device to rotate the device around a main left-turn axis at the left rear end portion or a main right-turn axis at the right rear end portion, such that the device turns one around one of the axes. The side walls are configured such that the device clears the obstacle by the turning motion.
