The invention relates to a method of cleaning the bottom of a pool with the aid of a pool cleaner. The pool cleaner travels along the bottom of the pool and collects material lying at the bottom of the pool. The pool cleaner is arranged to travel to and fro in straight, parallel paths between two opposite walls of the pool. At the walls the pool cleaner is turned by rotating a half turn so that, after turning, it will have been displaced laterally perpendicular to the initial direction of travel. |
