Home lawn sprinklers vary widely in their size, cost, and complexity. They include impact sprinklers, oscillating sprinklers, drip sprinklers, underground sprinkler systems, and portable sprinklers. Permanently installed systems may often operate on timers or other automated processes. They are occasionally installed with retractable heads for aesthetic and practical reasons, reducing damage during lawn mowing. These types of systems usually can be programmed to start automatically on a set time and day each week.

Small portable sprinklers can be placed temporarily on lawns if additional watering is needed or if no permanent system is in place. These are often attached to an outdoor water faucet and are placed for a short period of time. Other systems may be professionally installed permanently in the ground and are attached permanently to a home's plumbing system.

An antique sprinkler developed by Nomad called a 'set-and-forget tractor sprinkler' was used in Australia in the 1950s. Water pressure ensured that the sprinkler moved slowly across a lawn.
