1. Method of automatic controlling a self-moving device, especially a vacuum cleaner, with range-, respectively contact-sensors, wherein a closer area around the device is individually determined and scanned, e. g. by a movable arm, and wherein possible new positions at the borders of the closer area are stored and the device is then moved to a respective new position until no position can be selected anymore;

  • at this, the determination of the closer area and the selection of the position is realised mainly on the basis of the information of the surroundings, which is stored in a data field and updated in each step, at this, to determine the respective next position, an optimising out of all positions, which have been stored and can be approached by the device, is performed by calculating and comparing for each of these positions certain evaluation parameters, like distances or areas in the reach of a possible new position, which have not yet been scanned, and by selecting the position with the best evaluation result.
