Sunseeker L22 Robot Lawn Mower

The Sunseeker L22 is a boundary-wire robot lawn mower for yards up to 0.3 acres (13,000 sq ft). At 57 dB it's quieter than most household appliances — quiet enough to run at night without disturbing neighbors. Floating Cut Technology automatically adjusts the cutting deck to match terrain changes, preventing scalping and protecting the lawn. Ultrasonic obstacle detection, lift sensors, and tilt sensors keep it safe around people and pets. Rain sensor pauses mowing and returns the mower to base; IPX5 rated for easy hose-down cleaning. Backed by Sunseeker's 3-year warranty.
