Abstract
A device for use in a swimming pool includes an insert and a piston having a nozzle. The piston is carried in the insert for reciprocal movement between a lowered position and a raised position in which the piston is in one of a plurality of indexed orientations and the nozzle is above the insert. The piston rotates to an adjacent indexed orientation in response to reciprocation of the piston between the raised and lowered positions in response to the cyclical application of water through the insert. Upper and lower engagement assemblies prevent rotational movement of the piston in the raised and lowered positions. The upper engagement assembly includes upper teeth, lower teeth, and channels formed in the upper teeth which guide the lower teeth through the upper teeth as the piston moves from the lowered position to the raised position.
