A pool cleaning system, method of designing a pool cleaning system and method of making a pool cleaning system comprising origin cleaning heads, transition cleaning heads and debris capture zones. Transition heads comprising net water flow vectors may be positioned to establish net water flow in the direction of one or more debris capture zones. Transition heads may comprise incrementally rotating pool cleaning head assemblies or a recessed incrementally rotating nozzle assembly configured to establish the net water flow. Cleaning head structure may comprise a slidably rotatable reverser between upper and lower portions of a cam assembly, the slidably rotatable reverser adjustable between first and second positions such that an incrementally rotating stem slidably mounted to the cam assembly incrementally rotates clockwise when the reverser is in its first position and counter clockwise when the reverser is in its second position.

The swimming pool cleaning head of claim 5, wherein the second reverser tab is removably coupled to the nozzle head and a degree of nozzle head rotation between the first extent and the second extent is adjustably dependent upon positioning of the second reverser tab. 7. The swimming pool cleaning head of claim 6, wherein the first reverser tab is removably coupled to nozzle head. 8. The swimming pool cleaning head of claim 6, further comprising: a clamp ring coupled to the housing and configured to hold the cam assembly within the housing;one or more retainer installation lugs extending from the housing and positioned to selectively engage with body installation lugs of a body embedded in a pool surface to allow installation of the swimming pool cleaning head in only one direction. 9. The swimming pool cleaning head of claim 6, wherein the degree of nozzle head rotation is adjustable between approximately 23 and 360 degrees. 10. A swimming pool cleaning head assembly, comprising: a cam housing comprising a cam assembly within the cam housing, the cam assembly comprising an upper section comprising a first plurality of pin guides, a lower section positionally coupled to the upper section and comprising a second plurality of pin guides, and a slidable section positioned at least partially between the upper section and the lower section and comprising a third plurality of pin guides slidably mounted between the first plurality of pin guides and the second plurality of pin guides, the slidable section rotatable between a first extent and a second extent;a stem extending through the cam assembly;a nozzle head positioned at least partially within the cam assembly, the nozzle heading comprising at least one pin slidably engaged within the cam assembly between the first plurality of pin guides and the second plurality of pin guides, wherein rotation of the slidable section alters a pin path of the at least one pin through the first, second, and third plurality of pin guides, and rotation of the slidable section from the first extent to the second extent reverser a direction of travel for the at least one pin along the pin path. 11. The swimming pool cleaning head assembly of claim 10, wherein the first plurality of pin guides are formed between a first plurality of saw tooth members on the upper section, the second plurality of pin guides are formed between a second plurality of saw tooth members on the lower section, and the third plurality of pin guides are formed between a third plurality of saw tooth members on the slidable section. 12. The swimming pool cleaning head assembly of claim 11, wherein the at least one pin is configured to incrementally rotate the stem in a first direction in intermittent contact with the first, second, and third pluralities of pin guides during vertical translation of the stem through water pressure force applied to the stem, and slidably rotate the rotatable section of the cam assembly from the first extent to the second extent. 13.
