A rotating high pressure air and water nozzle is disclosed. The nozzle includes a head adapted to rotate, a housing adapted to secure the head therein, and a plurality of passageways disposed through the head. In addition, the nozzle includes a supply port disposed at a first end of each of the passageways, where each supply port has a funnel shape adapted to direct fluid into each passageway to reduce hydraulic losses, and a discharge port disposed at an opposing end of each of the passageways adapted to discharge a jet of fluid. Each discharge port is offset from the respective supply port to cause the head to rotate when fluid flows through the passageways.
