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.

1. A method of cleaning steps of a swimming pool, the method comprising: intermittently raising a nozzle head positioned on a step of the swimming pool under water, the nozzle head comprising at least a first nozzle opening and a second nozzle opening directed in different first and second nozzle directions toward a surface of the step, and simultaneously ejecting a first stream of water from the first nozzle opening toward a first, longer portion of the step and a second stream of water from the second nozzle opening toward a second, shorter portion of the step different from the first portion;incrementally rotating the nozzle head in a first rotational direction;retracting the nozzle head flush with an inner surface of the swimming pool; andincrementally rotating the nozzle head in a second rotational direction, opposite the first rotational direction, after the nozzle head rotates a predetermined number of incremental rotations in the first rotational direction and at least 45 degrees but not more than 180 degrees. 2. The method of claim 1, wherein the first nozzle direction and the second nozzle direction are at least 90 degrees different from each other. 3. The method of claim 2, wherein the nozzle head incrementally rotates between 13 to 15 times in the first rotational direction prior to incrementally rotating in the second rotational direction. 4. The method of claim 2, wherein the nozzle head further comprises a third nozzle opening directed in a third direction, different from the first direction and the second direction by at least 90 degrees, wherein the nozzle head incrementally rotates between 3 to 6 times in the first rotational direction prior to incrementally rotating in the second rotational direction. 5. The method of claim 2, wherein the nozzle head further comprises a third nozzle opening directed in a third direction, different from the first direction and the second direction by at least 90 degrees, and at fourth nozzle opening directed in a fourth direction, different from the first direction, and the second direction and the third direction by up to 90 degrees each, wherein the nozzle head incrementally rotates between 3 to 6 times in the first rotational direction prior to incrementally rotating in the second rotational direction. 6. The method of claim 2, wherein the nozzle head incrementally rotates between 8 to 10 times in the first rotational direction prior to incrementally rotating in the second rotational direction. 7. A method of cleaning a swimming pool, the method comprising: aiming an adjustable swimming pool cleaning nozzle head in a swimming pool with at least a first large nozzle opening facing in a first direction and at least a first small nozzle, smaller than the first large nozzle, facing in a second direction different from the first direction;raising the nozzle head under water in the swimming pool and simultaneously ejecting at least a first large stream of water in the first direction from the first nozzle opening and at least a first small stream of water, smaller than the first large stream of water, from the first small nozzle opening;rotating the nozzle head in a first rotational direction; andspraying the first large stream of water toward a first large area of a swimming pool along a width of a pool step and simultaneously spraying the first small stream of water toward a first small area of the swimming pool along a depth of the pool step. 8. The method of claim 7, further comprising simultaneously ejecting at least a second large stream of water in a third direction from a third nozzle opening in the nozzle head, the third direction different from the first direction and the second direction. 9. The method of claim 8, further comprising simultaneously ejecting at least a second small stream of water in a fourth direction from a fourth nozzle opening in the nozzle head, the fourth direction different from the first direction, the second direction and the third direction. 10. The method of claim 9, wherein the first direction, the second direction, the third direction and the fourth direction are each 90 degrees different from each other. 11. The method of claim 8, wherein the first direction and the third direction are 180 degrees different from each other and the first direction and the second direction are 90 degrees different from each other. 12. The method of claim 7, wherein the first direction and the second direction are 90 degrees different from each other. 13. The method of claim 7, wherein the first direction and the second direction are 180 degrees different from each other. 14. A method of cleaning a swimming pool, the method comprising: intermittently raising a nozzle head under water, the nozzle head comprising at least a first nozzle opening and a second nozzle opening directed in different first and second directions, and simultaneously ejecting a first stream of water outward from the first nozzle opening along a width of a pool step and a second stream of water outward from the second nozzle opening along a depth of the pool step;incrementally rotating the nozzle head in a first direction;retracting the nozzle head flush with an inner surface of the swimming pool; andincrementally rotating the nozzle head in a second rotational direction, opposite the first rotational direction, for a predetermined number of incremental rotations, after the nozzle head rotates the predetermined number of incremental rotations in the first rotational direction. 15. The method of claim 14, wherein the first and second directions are at least 90 degrees different from each other and the method further comprises incrementally rotating the nozzle head between 3 to 15 incremental rotations in the first rotational direction prior to incrementally rotating the nozzle head between 3 to 15 incremental rotations in the second rotational direction. 16. The method of claim 15, the nozzle head further comprising at least a third nozzle opening directed in a third direction different from the first and second directions by at least 90 degrees, the method further comprising simultaneously ejecting a third stream of water from the third nozzle opening while the first and second stream of water are being ejected, and incrementally rotating the nozzle head between 3 to 10 incremental rotations in the first rotational direction prior to incrementally rotating the nozzle head between 3 to 10 incremental rotations in the second rotational direction. 17. The method of claim 16, the nozzle head further comprising at least a fourth nozzle opening directed in a fourth direction different from each of the first, second and third directions by up to 90 degrees, the method further comprising simultaneously ejecting a fourth stream of water from the fourth nozzle opening while the first, second and third streams of water are being ejected, and incrementally rotating the nozzle head between 3 to 6 incremental rotations in the first rotational direction prior to incrementally rotating the nozzle head between 3 to 6 incremental rotations in the second rotational direction. 18. The method of claim 17, wherein the first and third nozzle openings are larger in diameter than the second and forth nozzle openings. 19. The method of claim 14, wherein the first direction and the second direction are between 45 degrees and 180 degrees different from each other.
