Buyer’s guide: robot mowers
How they work
Smaller models stay inside a boundary wire; newer ones use RTK satellite positioning, cameras or lidar with no wire. Large models carry reel or flail decks for fairways, verges and solar farms.
What to check before buying
- Area it can cover and slope limit
- Wire or wire-free, and what positioning it uses
- Theft protection and app control
