Abstract
Embodiments of the invention provide a system and method for operating a pressure-driven pool cleaner. The system includes a hydraulic timer assembly and a venturi vacuum assembly. The method includes directing water to the hydraulic timer assembly and the venturi vacuum assembly, driving the pressure-driven pool cleaner with the hydraulic timer assembly according to a timed movement cycle including a combination of backward movement and forward movement, and suctioning debris with the venturi vacuum assembly. The venturi vacuum assembly is independent of the hydraulic timer assembly so that suctioning occurs during the backward movement and the forward movement.
