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.
