The cheapest wire-free robot mower we list: camera navigation for small lawns of 1,000–2,000 sq ft.
Verdict: The lowest-cost way to try a robot mower, for small, simple lawns. Its 3.5-star rating and basic ultrasonic obstacle sensing mean you should expect more babysitting than pricier models.
Budget wire-free mower using GPS plus a camera, with row-then-random mowing and 35% slope handling.
Verdict: A well-reviewed budget pick for open lawns. Standard GPS isn't centimetre-accurate like RTK, so expect a partly random pattern rather than perfect stripes.
