Methods of cleaning a swimming pool using a swimming pool cleaning head. A first method may include intermittently raising a nozzle head under water and ejecting a stream of water under water, incrementally rotating the nozzle head in a clockwise direction, retracting the nozzle head, sliding a cam reverser, and reversing the direction of rotation of the nozzle head with the cam reverser to counterclockwise. A second method may include rotating a stem by sliding at least one pin coupled to the stem through at least one channel in a cam, the stem configured to release a stream of water under water in a swimming pool. The method may further include reversing the direction of rotation of the stem by sliding a slidable section of the cam with the at least one pin.
