A nozzle system (20) for imparting compound motion, including an orbital component and a rotational component, to the discharged fluid. The nozzle system (20) comprises a specially engineered shell (26) surrounding a freely flexible hose (28) of sufficient structural integrity to simultaneously exhibit two different motion characteristics to impart the compound motion to the discharged fluid. When fluid is delivered to the nozzle system (20). The hose (28) moves orbitally; that is, the hose (28) rotates or twists back and forth about its own axis relative to its fixed end. Both components of motion are imparted to the discharged fluid to enhance spray power and expanse.
