Robot lawn mowers

Robot mowers split cleanly on how they know where the lawn ends. Boundary wire means burying a perimeter wire once. RTK and vision mean setting a virtual boundary in an app, which costs more and takes an afternoon instead of a weekend.

What decides compatibility

  • Boundary wire is cheap and permanent, and it is a real install. RTK needs a clear sky view for the antenna and struggles under heavy tree cover.
  • Slope limit rules out plenty of yards. Check the rating against your steepest section, not the average.
  • Rated lawn area assumes a simple shape. Narrow passages and separate zones both cut real coverage.
  • Most keep their schedule in the maker's app. Home system support is usually start, stop, and dock.
