Oscillating sprinklers and impact sprinklers have distinct differences in their operation and application. Oscillating sprinklers move back and forth, creating a fan - shaped spray pattern. This makes them well - suited for rectangular areas, such as long, narrow lawns. They typically provide a relatively even but lower - pressure water distribution.
Impact sprinklers, on the other hand, rotate in a circular motion due to the force of the outgoing water. They are capable of spraying water over a much larger area, with some models reaching up to 85 feet in diameter. Impact sprinklers deliver water with more force, which is beneficial for large, open spaces but may be too intense for delicate plants. In summary, oscillating sprinklers are for targeted, rectangular - area watering, while impact sprinklers are for wide - scale, circular - area irrigation.
