Can a robot mower work without a boundary wire?
Short answer
Yes. Satellite-guided mowers such as Husqvarna's EPOS models mow inside virtual boundaries with no buried wire.
Which robots can do it?
- Husqvarna Automower 410 iQYes
Husqvarna lists the Automower 410 iQ among its EPOS models that mow without a boundary wire.
Good to know: Uses RTK satellite positioning; heavy shade may need some wire.
- Segway NavimowYes
Segway's Navimow mows without a boundary wire using RTK positioning, per a hands-on review.
Good to know: Reviewer had antenna trouble; signal can weaken under large trees. 2023 review of the line, not one model.
Why it matters
Burying a perimeter wire is the hardest part of owning a robot mower, and the wire breaks.
Not proven yet
Performance under heavy tree cover. Husqvarna itself says some wire may help in deep shade.
