Abstract
A pool cleaner for cleaning a pool includes a housing with an upper surface and downwardly projecting sidewalls extending from the upper surface for defining a front, a rear, a first and a second side of the housing. A first pair of wheels includes a first wheel being pivotally mounted relative to the first side of the housing and a second wheel being pivotally mounted relative to the second side of the housing. A tie rod is operatively mounted relative to the first wheel and the second wheel. A second pair of wheels is mounted on the rear end of the housing. As the pool cleaner traverses a pool surface and the first or second wheel is moved to be at a predetermined angular relationship relative to the housing, the tie rod ensures that the first and second wheels are at substantially the same angular relationship relative to the housing.
