Abstract
A zone of a floor to be cleaned is subdivided into a plurality of blocks, the position of each block is memorized in a memory of a self-running cleaning apparatus, and the status of each block such that a wall or an obstacle is placed on the block or the block is passed by the cleaning apparatus thereon is also memorized in the memory. The cleaning apparatus moves across the blocks having neither wall nor obstacle thereon and which have not been passed by the cleaning apparatus on the basis of a predetermined priority order in running direction.
