Most lawns need 1 to 2 inches of water per week to thrive. While rainfall can help provide that needed water, often Mother Nature alone won’t be able to meet every healthy lawn’s needs. An oscillating sprinkler can supplement the needed water and help maintain a beautiful and lush lawn.
Unlike other sprinkler types that distribute water in a circular pattern, this type of sprinkler has a sled base that supports a long sprinkler head fitted with up to 20 nozzles that shoot water in a square-shaped pattern. With its ability to cover nearly 5,000 square feet, an oscillating sprinkler is ideal for watering lawns. The coverage of these sprinklers also is adjustable, allowing the user to efficiently water gardens and flower beds without wasteful overspray.
In this guide, you’ll discover the features to consider when shopping for these watering devices and then discover some of the best oscillating sprinklers on the market.

What to Consider When Buying the Best Oscillating Sprinkler
Lawn size, the adjustability of the spray pattern, water pressure demands, and the construction of the sprinkler are some of the important factors to consider when choosing an oscillating sprinkler for a yard or garden. Keep reading to learn more about these and other factors to consider when shopping for the best oscillating sprinkler.
Lawn size will help determine the best sprinkler, as it’s helpful to purchase a sprinkler that will minimize the number of times it must be moved to cover the entire yard. To determine the area of the yard or garden, multiply its length by its width. Then use the area to shop for the appropriately sized sprinkler. For example, a lawn that is 50 feet by 75 feet would need a sprinkler that can cover at least 3,750 square feet.
Since oscillating sprinklers have a square-shaped coverage area, nonrectangular yards will require multiple sprinklers or a rotating sprinkler for full coverage. A larger yard also may need multiple sprinklers to cover the entire area in one watering session. Keep in mind that homes with water pressure below the standard 30 pounds per square inch (psi) won’t have enough pressure to meet the sprinkler’s maximum coverage standard.
Oscillating sprinklers consist of either plastic or metal parts, and each material has its pros and cons. Metal sprinklers will better endure accidental impacts from a lawn mower or errant soccer ball and serve as a sturdier base for the oscillating sprinkler head, but they are more prone to corrosion and rust. Sprinklers with plastic parts are more affordable but won’t hold up as well to impacts.
Oscillating sprinklers use a mechanism that moves the head back and forth slowly. Sprinklers that keep this mechanism in an enclosed chamber are more durable than models that have a drive exposed to the elements. Though this design is less expensive, the gears in the exposed drive can clog with dirt and debris, preventing the sprinkler from oscillating. With that in mind, a sprinkler with an open drive should be stored during inclement weather to protect these moving parts.
Unlike other sprinkler types, sled bases are not rooted to the ground by a stake, which can damage the yard. This design also makes it easy to maneuver them around the yard to cover multiple watering zones. Most sled bases are made of metal or plastic with an attachment for a standard garden hose and controls that adjust the range on one end.
Most oscillating sprinklers have a long sled base that measures about 15 to 17 inches long and 5 to 6 inches wide, although some oscillating sprinklers use a sled base with a circular design that measures about a foot in diameter. This large base provides a stable foundation that keeps the sprinkler steady as the head oscillates back and forth.
Oscillating sprinklers have a series of jets typically set in a line across an oscillating bar that sprays water up into the air. The jets are set at different angles to cover the watering area evenly. Most sprinklers have between 16 and 20 jets, with the latter providing the greatest amount of coverage. These jets oscillate back and forth at a consistent speed to allow for even watering across the entire coverage area.
The spray also is adjustable. Most oscillating sprinklers have an adjuster that controls how far the sprinkler head oscillates in either direction. Higher-end sprinklers usually allow the user to adjust the coverage area’s width, and some include a zoom knob that controls the size of the coverage area’s footprint.
Most oscillating sprinklers base their maximum coverage on 30 psi of water pressure, which suits the city water standard of about 30 to 50 psi that most homes use. If the available water pressure is less, the sprinkler won’t be able to reach the stated maximum coverage. If the water pressure is too low, the water may not generate enough force to turn the oscillating sprinkler head. Those with homes with water pressure that falls below this 30 psi threshold may consider a sprinkler designed for low pressure.
High water pressure also can have a negative impact on sprinkler performance, causing the water to mist as it exits the nozzles. A pressure regulator attached between the hose and the sprinkler can reduce this pressure. The best way to determine a home’s water pressure is to use a water gauge or flow meter.
Since an oscillating sprinkler can use about 17 gallons of water per minute, it’s important to look for features that help direct as much of that water to nourishing the lawn as possible. Oscillating sprinklers cover a fairly precise area, making it easy to position them to water desired areas and only those areas. This helps conserve water and prevents wasteful watering of driveways and sidewalks.
Some sprinklers include built-in timers. A sprinkler with a timer allows the user to set the sprinkler to shut off after a set amount of time, making it a great solution for preventing overwatering for those who don’t have a sprinkler control system.
Some oscillating sprinkler models include features that make them more convenient to use. This includes adapters that attach to the hose end, which makes attaching and detaching the sprinkler easier. They eliminate the need to screw and unscrew the connector when it’s time to store the hose or the sprinkler.
Most oscillating sprinklers also include built-in strainers, which prevent debris from entering the sprinkler and clogging the nozzles. Higher-end oscillating sprinklers also have flow controls that allow the user to adjust water output.
Some sprinklers include built-in timers, which will shut off the sprinkler after a preset period of time, preventing overwatering.
