Abstract
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.
