Guided reciprocating in-floor pool cleaner head

A device for use in a swimming pool structure, the swimming pool structure including a pool and a circulation system having a piping assembly and a pump for cyclically communicating water through the piping assembly between the pool and the pump, and the piping assembly terminating in a collar installed in the swimming pool structure, the device comprising:

• an insert defining a chamber coupled in fluid communication to the piping assembly through an inlet in the insert;
• a piston including a nozzle, the piston carried within the chamber 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 free of obstruction 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 flow through the chamber;
• upper and lower engagement assemblies prevent rotational movement of the piston with respect to the insert in the raised and lowered positions, respectively, of the piston;
• and
• guide means formed in the upper engagement assembly guide rotational movement of the piston during reciprocation of the piston between the raised and lowered positions.
