Embodiments provide a pool cleaner with a housing, a first drive wheel positioned along a first side of the housing, and a second drive wheel positioned along a second side of the housing. The pool cleaner also includes a steering system engaged with the first drive wheel and the second drive wheel. The steering system includes a rotating cam with a first cam profile and a second cam profile different from the first cam profile. The steering system drives the housing in a cycle of forward and turn movements by rotating the first drive wheel based on the first cam profile and rotating the second drive wheel based on the second cam profile.

Two-wheel actuator steering system and method for pool cleaner

Embodiments of the invention provide a paddle wheel mechanism for a pool cleaner. The paddle wheel mechanism includes a housing with an internal flow area, a paddle wheel shaft supported by the housing, and a paddle wheel supported by the paddle wheel shaft. The paddle wheel includes a base extending along a base width and a plurality of paddle wheel blades extending from the base within the internal flow area. The plurality of paddle wheel blades include a first-type blade with a first blade portion having a first blade width, and a second-type blade with a second blade portion having a second blade width. The first blade width and the second blade width are each less than the base width, and the first-type and second-type blades are arranged on the base in an alternating manner.

Alternating paddle mechanism for pool cleaner

Some embodiments provide a pool cleaner including a first drive wheel, a second drive wheel, a turbine paddle, and a steering system. The turbine paddle is configured to rotate based on water movement through the pool cleaner. The steering system is engaged with the first drive wheel, the second drive wheel, and the turbine paddle and is driven by rotation of the turbine paddle. The steering system includes a cam with a first cam profile and a second cam profile different from the first cam profile. The steering system is configured to drive the pool cleaner in forward, reverse, and turn movements by rotating the first drive wheel based on the first cam profile and rotating the second drive wheel based on the second cam profile.
