How to Pick a Robot Lawn Mower
Wire-free (GPS/vision) or boundary wire?
Wire-free models (Navimow, LUBA, Landroid Vision) set up in minutes and adapt to landscaping changes instantly. Boundary wire models (Husqvarna, Gardena, Greenworks) cost less per acre and work under dense tree cover where GPS struggles. If your lawn has open sky: go wire-free.
How big is your lawn?
Under 1/8 acre: Navimow i105 or Gardena SILENO. 1/4 to 1/2 acre: Landroid Vision or Greenworks Optimow. Over 1/2 acre or multi-zone: Husqvarna 430X or Mammotion LUBA 2.
Do you have steep slopes?
Standard mowers handle 30-35%. Husqvarna 430X manages 45%. For anything steeper — terraced yards, hills — only the AWD Mammotion LUBA 2 (80%) will not get stuck.
Is it safe with kids and pets?
All 6 models have lift and tilt sensors that stop blades instantly. Vision-based models (Navimow VisionFence, Landroid Vision) additionally detect and route around pets, toys, and feet before contact.
Do robot mowers actually save money?
A lawn service averages $50-100/visit — $1,200-2,400/season. Even the premium Husqvarna 430X pays for itself in 1-2 seasons, and electricity costs roughly $10-15 per season.
