Wire-free robot mowers compared: what do you actually get?
Full specifications21 measurements · 65 of 84 documented
How does each mower see its own boundary?
None of these four bury a wire. Each instead leans on a different mix of onboard camera vision, stored maps, and satellite positioning to hold a line.
TerraMow V1000
Ecovacs Goat GX-600
Worx Landroid Vision M800
AIRSEEKERS Tron SEAIRSEEKERS' own comparison page documents VSLAM fused with NetRTK satellite positioning, the only stack among these four adding satellite correction to camera vision.
RobotMower.Info and Robotop.fr describe the Landroid Vision classifying each camera frame as grass or not-grass roughly twenty times a second, with nothing stored between runs.
Ecovacs and TerraMow each document a retained boundary map built during setup: SmartMove maps over the first mowing runs, and the V1000 maps through a single app-guided walk.
How much yard does each one cover?
Rated coverage areas differ across the four mowers, and one manufacturer publishes two separate figures for the same unit depending on yard complexity.
TerraMow V1000Ecovacs Goat GX-600Worx Landroid Vision M800AIRSEEKERS Tron SEAIRSEEKERS' manufacturer comparison lists 1,500 sq m as optimal total coverage but only 400 sq m per charge in complex layouts, the only figure among these four split that way.
Ecovacs rates the GX-600 for 600 sq m and a 40 percent slope grade, both published on the manufacturer's own product page.
Worx publishes an 800 sq m rated area and a 30 percent slope maximum for the Landroid Vision M800 on its EU product page.
What does each mower physically weigh and measure?
Coverage claims aside, the four mowers differ in size and weight, from a compact 26-pound unit to a machine over 40 pounds.
TerraMow V1000Ecovacs Goat GX-600Worx Landroid Vision M800AIRSEEKERS Tron SEAIRSEEKERS documents dual rear-wheel direct-drive brushless hub motors paired with 12-segment omnidirectional front wheels, a drive layout none of the other three manufacturers describe in comparable detail.
TerraMow, Ecovacs, and Worx each publish dimensions and weight on their own product pages, checked directly against each listing for this comparison.
How deep is each one's independent evidence record?
Published source counts range from a single review to owner reports tracked since 2023 for the oldest model, and two of these four mowers have almost no independent record yet.
TerraMow V1000Ecovacs Goat GX-600Worx Landroid Vision M800AIRSEEKERS Tron SEComputerBild, RobotMower.Info, Robotop.fr, and loggn.de each published extended-use accounts of the Landroid Vision M800, the only mower here with that depth of independent testing.
AIRSEEKERS' record states plainly that no extended-use review, owner forum, or trade repair source specific to the Tron SE was located.
TerraMow's classification rests on a single 2026 Wired review alongside TerraMow's own manufacturer specifications, with no independent owner-report source yet on file for this recently introduced model.
What upkeep parts are actually priced?
Setting aside multi-year cost projections, each manufacturer names and prices a different slice of the parts an owner will eventually replace.
TerraMow V1000Ecovacs Goat GX-600Worx Landroid Vision M800AIRSEEKERS Tron SEWorx documents a 20 to 30 mowing-hour blade life at $35 to $45 per set, a usage-based interval none of the other three manufacturers publish.
AIRSEEKERS prices an 18-pack of spare blades at $29, a mowing disc at $39, and a two-pack of drive wheels at $109 on its own parts pages.
Neither TerraMow nor Ecovacs publishes a blade price; TerraMow names only a seasonal replacement cadence, and Ecovacs ships a spare set with no listed cost.
In closing
What the evidence shows
Patterns that emerged across the questions above.
Evidence depth tracks time on the market
Worx and Ecovacs have been sold since 2023 and 2024, with owner reports and multi-year firmware notes to show for it; TerraMow's release date and AIRSEEKERS' evidence stop at manufacturer and announcement-level sources.
Boundary sensing takes three different forms
Two mowers hold a stored map, one classifies grass fresh from every camera frame with nothing retained, and one fuses that vision with satellite RTK positioning.
Priced maintenance parts vary by manufacturer
AIRSEEKERS names prices for blades, a mowing disc, and drive wheels; Worx publishes a blade interval in mowing hours; TerraMow and Ecovacs leave replacement costs undocumented.
