摘要
Swimming pool in-floor cleaning heads may be used to variably clean a swimming pool floor by raising a nozzle head positioned on a step of the swimming pool under water and having at least first and second nozzle openings directed in different directions toward surfaces of the step, and simultaneously ejecting first and second streams of water from the first and second nozzle openings toward, respective, first and second portions of the step, variably rotating the nozzle head in a first rotational direction, retracting the nozzle head flush with an inner surface of the swimming pool, and in some cases incrementally rotating the nozzle head in a second direction, opposite the first direction.
