ABSTRACT:
A method for automatically controlling a travelling and cleaning operation of a vacuum cleaner. The method comprises a learning travel step for calculating and storing straight travelling distances of outline paths and path directions together with the total number of the outline paths, a two-dimensional coordinates calculating step for determining positions of straight division lines by using data of the travelling distances and the path directions, and calculating two-dimensional coordinates of cleaning blocks determining positions and areas of the cleaning blocks, a cleaning block discriminating step for discriminating integrated cleaning regions each comprising a plurality of sequential cleaning blocks of which each lower end or upper end coincides with an outline path of the cleaning region, and determining a cleaning start block and a cleaning end block of the integrated cleaning region, and a practical cleaning step for controlling the cleaner to travel along a travelling path from a cleaning start block to a cleaning end block of the integrated cleaning region, and turn in 180.degree. turning reverse, then travel from the cleaning end block to the cleaning start block simultaneously with overlapping the cleaning blocks in a predetermined overlapping value.
