Abstract: An automatic pool cleaner comprising a housing and a base. The housing comprises a suction flow pathway, an impeller disposed within the housing and in fluid communication with the suction flow pathway such that water traveling through the suction flow pathway spins the impeller, wherein spinning of the impeller causes the pool cleaner to move forward, an off-center cam that extends through the impeller and is configured to rotate as the impeller rotates, and two spring biased valves. Each valve comprises a valve seat, and a spring biased poppet configured to seal against the valve seat, the poppet having a rod with a spring disposed around the rod. The base comprises two feet, each foot having a spring-biased pad extending from each end of the foot, two A-arm assemblies, one for each foot, and a suction port that extends through the base.
