Wire-free robot mowers and trees: which ones cope?
Where it stands
As of Oct 22, 2026: wire-free mowers are on sale. Under heavy trees, models with LiDAR or cameras do better than satellite-only ones.
Skipping the boundary wire is the main reason to buy a new robot mower, and "will it work under my trees?" is the question that follows. The answer depends on how the mower knows where it is.
Why do trees cause trouble?
Most wire-free mowers use RTK, a precise form of satellite positioning that needs a clear view of the sky. Under large trees the signal weakens, and the mower can lose track of its boundaries. Husqvarna itself says some wire may still help in heavy shade.

What helps?
Adding a second way to see. In Notebookcheck's side-by-side test, the RTK version of the Mammotion Luba Mini suited gardens without many trees or buildings, while the LiDAR version, which doesn't rely on satellites, was the better choice for yards with lots of trees.

Which mowers have we checked?
Mammotion Luba 3 AWD (from $2,399): satellite positioning plus LiDAR and cameras. 9to5Google found it held its lines almost perfectly, but it got stuck at a ditch when positioning drifted a few inches. Techaeris describes it as reliable under heavy tree canopy.
Ecovacs Goat O800 RTK (from €699 in Europe): rated good in Netzwelt's German test, with good obstacle and edge detection, though satellite reception was stubborn at first.
Husqvarna Automower 410 iQ and Segway Navimow: RTK-based, wire-free, and both noted to weaken in heavy shade.

Does a wire-free mower do all the work?
No. After weeks with the Luba 3, 9to5Google still trimmed edges, weeds and spots along the driveway and fence by hand. It cut weekly mowing from an hour or two to a few minutes.

Does the new FCC rule affect mowers?
It can. The FCC's July 2026 restriction on new foreign-made robotic devices is written broadly enough to cover robot mowers that meet its criteria. Models already authorized can still be sold; new models would need a Conditional Approval.

How we know (9 sources)
Hands-on review of Segway's Navimow line, which uses RTK positioning instead of a boundary wire. The reviewer hit some antenna difficulties; signal can weaken under large trees.
Read the sourceHusqvarna's EPOS page: satellite (RTK) positioning lets Automower models mow inside virtual boundaries with no boundary wire. Lists models including the 410 iQ, 420 iQ and 440 iQ. Notes some wire may still help in heavy shade.
Read the sourceExplainer on boundary-wire versus wire-free robot mowers. Wired models tend to cost less, but the wire takes time to lay and must be moved when the lawn changes. Wire-free models use GPS, cameras and sensors, cost more, and can be less precise when the GPS signal is weak. Suggests wired for small, simple lawns on a budget.
Read the sourceSide-by-side test of the Mammotion Luba Mini AWD with RTK and with LiDAR. The RTK version suits gardens without many trees or buildings blocking satellite signals; the LiDAR version doesn't depend on those signals and is the better choice for yards with lots of trees. RTK versions from $1,599 RRP.

Read the sourceSeveral weeks with a Mammotion-supplied Luba 3 AWD, which uses network RTK plus LiDAR instead of a boundary wire. It held its mapped lines almost perfectly, but got stuck at a ditch when positioning was off by a few inches. Trimming and edging are still needed. From $2,399 in the US.
Read the sourceReview of the Luba 3 AWD (3000 model, $2,799 MSRP), scored 9.1/10. Its LiDAR, RTK and camera navigation is described as reliable under heavy tree canopy where RTK-only mowers lose signal. Downsides: price, occasional grass damage on sharp turns, app lag, weight.
Read the sourceGerman hands-on test of the Ecovacs Goat O800 RTK, a wire-free RTK mower: grade 1.6 (good), with good obstacle detection and very good automatic edge detection. Satellite reception was stubborn at first, and it had slight trouble on slopes when wet. From €699.
Read the sourceExplainer (last updated Sep 9, 2026) on the FCC adding foreign-produced advanced robotic devices to its Covered List on July 28, 2026. New foreign-made models can't get the FCC authorization needed to be sold in the US unless they qualify for Conditional Approval. Robots you own, already-authorized models and new units of them are not affected. The definition fits most robot vacuums and can also cover robot mowers and humanoids.
