Pop-up sprinklers are a type of irrigation system designed to water lawns and gardens efficiently. They are installed underground and rise above the ground when activated, spraying water in a specific pattern. Once the watering cycle is complete, they retract back into the ground, making them less obtrusive and safer for mowing. These sprinklers can be adjusted to cover different areas and can be connected to timers or smart irrigation systems for automated watering. They are commonly used in residential and commercial landscapes, providing a convenient way to maintain healthy plants and grass while conserving water.
