Pool cleaner with hydraulic timer assembly
First Claim
1. A pool cleaner, comprising:
- a chassis;
a cover assembly supported by the chassis;
at least one drive wheel supported by the chassis;
a turbine assembly which rotates in one of a first direction and a second direction to drive the at least one drive wheel; and
a timer disc assembly including at least one rotating timer disc that controlsa flow of pressurized fluid away from the cover assembly 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, anda 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.

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.

13. A pool cleaner, comprising:
-
a chassis; a cover assembly and at least one drive wheel supported by the chassis; a turbine assembly in communication with the at least one drive wheel; and a timer disc assembly including at least one rotating timer disc that controls a flow of pressurized fluid to the turbine assembly by rotating to a first position to cause alignment with a first outlet port for driving the turbine assembly in a first direction during a first time period, and rotating to a second position to cause alignment with a second outlet port for driving the turbine assembly in a second direction during a second time period. - View Dependent Claims (14, 15, 16, 17, 18)
