ABSTRACT:
An improved drivehead for an automatic swimming pool cleaning system includes a circular wheel member mounted for free rotation around a platform member. The platform member carries a water jet nozzle which urges the wheel member into rolling contact with and along the sides of the pool. A flexible water supply hose connects the platform member to a pressurized pool water inlet. The water jet nozzle and supply hose cooperate, when the drivehead encounters an obstruction, to cause the platform member to rotate within the outer wheel member to move the drivehead around the obstruction.
