A pool cleaner for cleaning a pool surface includes a wing having an inner edge, a lower outer edge, and an underside extending between the inner edge and lower outer edge. The inner edge and lower outer edge depend from the underside. Engagement holes formed through the inner edge are configured to and capable of non-rigidly engaging the wing to a pool cleaner. Projections are carried on the underside of the wing, and the projections extend beyond both the inner edge and the lower outer edge.
