A pool cleaner with a cover assembly that includes a bottom cover with a cover opening, a supply mast, a distributor manifold, a timer assembly, a scrubber assembly, and a venturi vacuum. The distributor manifold receives water from the supply mast and encircles the suction mast. The venturi vacuum is in fluid communication with the distributor manifold and is designed to vacuum debris from a pool surface.

Pool cleaner with hydraulic timer assembly

A pool cleaner comprises a housing including at least two wheels, a supply mast, and a timer disc assembly configured to receive water from the supply mast. The timer disc assembly includes an outer housing, a plurality of outlet ports extending through the outer housing, and a rotating timer disc positioned within the outer housing adjacent to the plurality of outlet ports. The timer disc assembly also includes at least one stationary port seal liner positioned between one of the plurality of outlet ports and the rotating timer disc. The at least one stationary port seal liner includes an elastomeric piece and a liner piece, and the liner piece is in contact with the rotating timer disc.

According to some embodiments, a pool cleaner includes a chassis, a housing supported by the chassis, at least one drive wheel supported by the chassis, and a turbine assembly that rotates in one of a first direction and a second direction to drive the at least one drive wheel. The pool cleaner also includes a timer disc assembly with at least one rotating timer disc. The timer disc assembly controls a flow of pressurized fluid away from the housing in a forward direction for backward propulsion assistance of the pool cleaner during a first time period, a rearward direction for forward propulsion assistance of the pool cleaner during a second time period, and a sideways direction for turning propulsion assistance of the pool cleaner during at least a portion of one of the first time period and the second time period. The timer disc assembly also controls a flow of pressurized fluid to the turbine assembly through a first opening for driving the turbine assembly in the first direction during the first time period and a second opening for driving the turbine assembly in the second direction during the second time period.

Some embodiments include a debris bag for a pool cleaner. The debris bag includes a sheet of filtration media that forms an opening and a hollow interior portion to capture debris from the pool cleaner. An attachment fixture is located at the opening and includes a ring having a hook area for coupling the attachment fixture to an outlet of the pool cleaner.

Biodegradable disposable debris bag

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.

Embodiments of the invention provide a biodegradable, disposable debris bag for a pool cleaner. The debris bag includes biodegradable fabric filtration media stitched together to form an opening capable of being coupled to an outlet of the pool cleaner and a hollow interior portion to capture debris from the pool cleaner. The biodegradable fabric filtration media is folded over and stitched together to create the opening and the hollow interior portion.
