Best robot lawn mower without a perimeter wire

Other models on most shortlists

These models come up when people ask this question. Here are their makers’ figures and price, to set beside our pick above.

How wire-free mowers find their way

A mower with no wire has to know where your lawn ends. It does that with satellites, a camera, a laser (LiDAR), or a mix. Trees are the big test. Leaves block the satellite signal, so a mower that uses satellites alone can lose its edges in shade.

In the makers’ own words:

• Satellites only (RTK). Husqvarna’s system uses “multiple satellites and the national cellular network” to know where the mower is (Husqvarna). Husqvarna says that where the satellite signal is weak, the edges you draw in the app “may be compromised” (Husqvarna). Examples: Husqvarna Automower 410 iQ, Husqvarna Automower 435iQ AWD, Husqvarna Automower 420 iQ.
• Satellites + camera. Satellites give the map. A camera backs them up. WORX says “when trees or buildings block satellite signals”, the mower switches to its camera and motion sensors (WORX). The camera holds the route only “until satellites return”, WORX says (WORX). Examples: WORX Landroid Vision Cloud WR320, Segway Navimow i110N, WORX Landroid Vision Cloud 1/4 Acre, Ecovacs GOAT O1000 RTK.
• Camera only. No satellites at all. WORX says its Vision model uses “its sophisticated camera to identify grassy areas” (WORX). eufy says “No Wires, No RTK, No Signal Issues” (eufy). The largest camera-only mower we track is rated for 8,712 sq ft, well under half an acre. Examples: WORX Landroid Vision AI 1/2 Acre, eufy E15.
• LiDAR (laser), most with satellites. A laser scanner adds its own view of the yard. Mammotion’s LUBA 3 combines “360° LiDAR, NetRTK, AI Vision” (Mammotion). Segway says its H2 keeps its course “even under trees, in narrow paths, at night” (Segway). The lowest list price among the LiDAR mowers we track is $1,559. Examples: Mammotion LUBA mini 2 AWD 1500H, Mammotion LUBA 3 AWD 3000H, Segway Navimow H210, Mammotion YUKA mini 2 1000H.

About the name: WORX sells the Landroid Vision WR220 as the “1/2 Acre” model, but its own page says it “Reliably covers areas up to 1/5 acre (8,712 sq. ft.)”. We judge it on 8,712 sq ft, about a fifth of an acre (WORX’s page, read October 1, 2026).

RTK corrects the satellite fix so the mower knows where it is to within inches; Ecovacs, for one, claims “0.8 inch precision” (Ecovacs). Some mowers get that correction over the internet. Others need a small antenna (a “reference station”) set up in your yard. The next sections say which.

Which ones are rated for half an acre

Every robot mower has two limits its maker prints: how much lawn it can keep cut, and how steep a slope it can climb. Stay under both. 7 of the 17 wire-free mowers we track are rated for half an acre or more. Amazon sold 2 of them new on November 2, 2026: the Husqvarna Automower 410 iQ and WORX Landroid Vision Cloud WR320.

What you set up, and what you pay after

No wire still means some setup. Some mowers need a small antenna in the yard. Most need a data service for the app and theft tracking. Here is what each pick needs, from the makers’ pages.

• WORX Landroid Vision Cloud WR320

  • You set up: Nothing. WORX says there is “no hardware to install at home” (WORX).
  • Data service: “Lifetime free” RTK Cloud service, WORX says (WORX).
  • If it is stolen: You can find it from the app, even when it is off (WORX). It starts only with your PIN (WORX manual).

• Husqvarna Automower 410 iQ

  • You set up: Husqvarna’s kit includes an “RS1 EPOS reference station” (Husqvarna). Put the charging dock where it has an “unimpeded sky view” (Husqvarna).
  • Data service: A “10-year mobile data contract” comes with Automower Connect, Husqvarna’s app service (Husqvarna FAQ).
  • If it is stolen: A loud alarm if it is picked up, GPS tracking in the app, and a PIN (Husqvarna; GPS; PIN).

• Ecovacs GOAT O1000 RTK

  • You set up: A reference station on a pole. It comes in the box (Ecovacs).
  • Data service: We found no data plan on Ecovacs’s product or help pages.
  • If it is stolen: No GPS tracking. Ecovacs says this GOAT “does not have GPS capability” (Ecovacs). You can turn on a lift alarm (Ecovacs).

Why these three

We do not test mowers. Each pick follows a rule on the makers’ own figures, and price decides only between mowers that are rated for the yard. The same WORX wins both the open half acre and the half acre with trees: it is the only mower on Amazon rated for half an acre that does not steer by satellites alone.

WORX Landroid Vision Cloud WR320

For: Half an acre, open lawn or trees

WORX rates it for 21,780 sq ft (half an acre) and a 30% slope. No mower on Amazon rated for half an acre costs less. It steers by satellites plus a camera: WORX says the camera “creates a 3D model of edges and features” while the satellites keep the coordinates (WORX). When trees block the sky, it keeps going on the camera and motion sensors “until satellites return” (WORX). There is nothing to install and no fee for the satellite correction. The warranty is 3 years.

The catch: half an acre is its limit, so a full half-acre lawn uses all of it. Its 30% slope limit is fine for most yards but not a steep bank. WORX does not publish its run time and noise level.

Husqvarna Automower 410 iQ

For: Half an acre with a steep slope

Husqvarna rates it for a 45% slope, the steepest of any mower on Amazon rated for half an acre, and for 21,780 sq ft of lawn. Husqvarna adds “±20%” to that size (Husqvarna). It has lift and tilt sensors, and its blades “automatically and immediately shut off” when it is lifted (Husqvarna; Husqvarna FAQ). The warranty is 4 years, the longest of the picks.

The catch: it steers by satellites only. Husqvarna says boundaries “may be compromised” where the signal is weak (Husqvarna). Under a lot of trees, pick the WR320 unless the slope rules it out. It costs $1,112 more than the WR320.

Ecovacs GOAT O1000 RTK

For: Lowest price, up to a quarter acre

Ecovacs rates it for 10,890 sq ft (a quarter acre) and a 45% slope, which it also writes as “45% (24°)” (Ecovacs). It is the lowest-priced wire-free mower on Amazon rated for a quarter acre. Ecovacs says it “works reliably even in shaded areas” and under trees (Ecovacs), and that it avoids “200+ obstacles” (Ecovacs).

The catch: you set up its reference station on a pole in the yard. It has no GPS tracking if stolen. And it is rated for a quarter acre, so it is not for a half-acre lawn.

How each pick was chosen. Half an acre: rated for the half acre and its slope with no wire; the best fit, then the lowest Amazon price. With trees: rated for the half acre with no wire, and it does not steer by satellite alone; then the lowest Amazon price. Steep slope: rated for the half acre with no wire; the highest published slope limit, then the lowest Amazon price. Lowest price: rated for at least a quarter acre with no wire; the lowest Amazon price.
