“Wobbler technology is totally different in its method of water distribution. Instead of distributing water as a fan type spray or through a fixed nozzle onto an oscillating arm, the stream is directed at the center of a rotating deflector. Based on the water pressure, the rotating grooved deflector distributes consistent sized droplets in a circular area. Using multiple Wobblers with head-to-head spacing in rows, very high uniformity of distribution is reached.”
