ROBOT MOWERS · BUYING DECISION
Wire-free versus boundary-wire robot mowers
Boundary wire provides a physical perimeter signal; wire-free systems create virtual boundaries using satellite, vision or LiDAR-based positioning.
The short answer
Boundary wire provides a physical perimeter signal; wire-free systems create virtual boundaries using satellite, vision or LiDAR-based positioning.
What changes the decision
Wire-free does not mean constraint-free. RTK placement, satellite visibility, camera conditions and map stability matter. Boundary wire adds installation and repair work but can avoid some positioning dependencies.
