Abstract:
1. A method of controlling the directional movement of a self-propelled robotic pool cleaner while cleaning a pool comprising the steps of: (a) propelling the pool cleaner in a first direction along a generally straight path away from a first sidewall toward an opposing sidewall of the pool, wherein said pool cleaner is propelled to a turning point in the pool that is at a distance greater than the midpoint between the first sidewall and the opposing sidewall and displaced from the opposing sidewall of the pool; (b) stopping the pool cleaner at the turning point and radially pivoting the pool cleaner at a first angle with respect to the first direction to cause a predetermined angular change in direction; and (c) resuming the propulsion of the pool cleaner in a reverse direction to return to the first sidewall in a second direction along a generally straight path that is angularly displaced from the first direction.
