Abstract
A pool cleaner for cleaning a pool surface includes a chassis, arms mounted to the chassis for oscillatory movement in response to water being drawn through the pool cleaner and rotating a drive assembly operatively coupled to the arms, a wing mounted to each of the arms for flapping movement in response to the oscillatory movement of the arms, and projections carried on an underside of the wings for disturbing material from the pool surface to be cleaned by the pool cleaner.
