Abstract
A method for accurately controlling the directional and turning movement of a self-propelled robotic pool cleaner while cleaning a pool includes the steps of propelling the pool cleaner in a first direction along a generally straight path from a first sidewall toward an opposing sidewall of the pool, wherein said pool cleaner is propelled to a position in the pool corresponding to a distance greater than the midpoint between the first sidewall and the opposing sidewall and before contacting the opposing sidewall of the pool; stopping the pool cleaner at the position and pivoting the pool cleaner to a predetermined angular change in direction; and reversing direction and resuming propulsion of the pool cleaner, wherein the pool cleaner moves in a second direction along a generally straight path that is angularly displaced from the first direction.
