Lymow One Plus

Name: Lymow One Plus
Brand: Lymow

10 TOPS on-board compute drives Level III autonomy in wire-free yards. Rubber tracks and a rated 100 percent (45 degree) slope limit put it on ground wheeled mowers cannot hold. Twin SK5 tool-steel cutting discs mulch growth that lighter decks stall in.

Autonomy Ladder

Why Level III.

One five-rung scale, every category, from acting only on command to working unsupervised anywhere.

VGeneralized AutonomyAny task, any setting. No consumer robot has reached it.
IVEnvironmental AutonomyCopes with everyday clutter and frees itself, shown by independent testing.
To reach Level IVIndependent testing shows it avoids ordinary obstacles before contact, copes without the space being cleared, and frees itself when stuck.
IIIConditional AutonomyThis robot

Lymow One Plus finishes whole jobs in a space it already knows, and still needs a person at the edges.

Navigation and control

RTK positioning + stereo-camera vSLAM + 10 TOPS on-board AI
Why this level
- PCWorld and Basic Tutorials report consumer units mowing on their own and detecting toys, furniture, sprinklers and branches before contact, avoiding obstacles in nearly all test situations.
- Level IV is not met on recovery: Basic Tutorials saw it stop on the lawn instead of returning to its base and unexpectedly abandon routes, and neither it nor TechAeris reports that rescue is rare.

DeficientLimitedCapableStrongExemplary

Measured on 7 of the 9 inputs26% not counted

Our assessment did not establish an independent source for edge-case recovery, field failure rate on this machine, so those inputs are left out of the score rather than guessed at, and the rest re-weighted to fill the space. A gap in what we have been able to verify is not evidence against the robot. Where a whole pillar has nothing measured, we publish no number at all.

Capability40% of the score78What it does without you.

Task completion16% of the score75

Evidence

TechAeris ran the One Plus for several weeks on a lawn with "many rolling hills, rocks, mole mounds, undefined borders, obstacles, and other oddities" and concluded it "does an excellent job when you calm down and take it slow," while at maximum speed and power settings "it created chaos," so the owner tunes the run to get a complete cut. PCWorld's test site adds that "the cut is impressive after the first mowing session" with the mulch finely distributed.

Coverage and navigation10% of the score75

Evidence

PCWorld, on its own test site, reports the mower "starts up quickly and works in straight lines" over a manually traced map that took "around 30 to 45 minutes" to lay out, with zones that can be "created, separated, or merged, even retrospectively" and up to 80 zones stored. The same review names the manual reset case directly: "If the RTK antenna is moved later, the entire map must be recreated."

Edge-case recoverynot countedno source verified58

Evidence

Real pre-contact perception, a front camera feeding AI Vision on 10 TOPS of onboard compute plus five ultrasonic sensors, and tracks that reduce the soft-ground entrapment cases before recovery is needed. What is absent is the recovery itself: no recovery behavior is documented anywhere on this record, degraded-fix response is explicitly unpublished, and the record notes there is no boundary fallback if RTK is lost near tall structures. Drivetrain wear is not self-recoverable either, since track tension service every 12 to 24 months requires manufacturer support.

Operating envelope4% of the score96

Evidence

Rated to 100 percent grade, 45 degrees, on tracks that hold wet and uneven ground, and the deck is built for Bermuda, fescue, bluegrass and zoysia rather than one prepared turf type. Discounted against the rating rather than to it, because the one independent measurement the record cites, PCWorld's reviewer, reports reliable performance around 30 degrees in use, which is 15 degrees under the spec. Signal loss near tall structures and a 78.5 pound machine are the other documented limits.

Dependability40% of the score68Whether it keeps doing it.

Field failure ratenot countedno source verified34

Evidence

Evidence floor under rule 2. Five months in market as of scoring, and the source list is the Lymow product page, the Lymow homepage and one aggregator site, with the PCWorld reading cited in prose but never linked. No relief from the predecessor rule: the Lymow One is only sixteen months old and its own record is equally unevidenced, so there is no mature platform history to inherit. The published 12 to 24 month factory track tension service suggests drivetrain wear is an anticipated path rather than an outside case.

Software stability14% of the score82

Evidence

No firmware source, no changelog, no release history and no support portal appear on this record, from a manufacturer with no update track record to inspect. Updates presumably ship over the 4G link and no owner reports a regression, which keeps it off the bottom anchor, but placed below the ordinary-case value because there is not even a documented channel here. Absence of a changelog is not stability.

Support longevity10% of the score48

Evidence

Better than its stablemate the Lymow One and still weak. In its favor, and unusually specific for this category, the record carries published figures for both parts and labor: a blade cartridge at $80 to $150 and a track tension service at $150 to $250, which implies a real service channel rather than an assumed one. Against it, no dealer network, no published support term, a single-product manufacturer, and a 4G SIM that is free for one year with the renewal cost unpublished on a machine that connects whenever it runs.

Ownership burden20% of the score73What it asks of you.

Routine maintenance12% of the score75

Evidence

Notably lighter than the Lymow One's schedule with the same drivetrain: monthly camera and side-sensor lens cleaning, dock contact inspection every three to six months, seasonal track tread and sprocket cleaning, an annual blade cartridge change with RTK antenna recalibration, and as-needed dock alignment. Nothing weekly and no after-every-use step. Held down by an unusual item: a track tension service every 12 to 24 months that the owner cannot perform.

Consumables8% of the score69

Evidence

An annual blade cartridge interval is among the best in the category and the cartridge price is the worst, $80 to $150 a set against $20 to $30 for a Husqvarna blade and screw set, so the cadence advantage is largely spent. Two costs beyond blades push this below its interval: $150 to $250 of labor for the biennial track service, and a 4G SIM free for the first year with no published price thereafter, which the record lists as a con for exactly that reason.

middle half of the databaseits medianthis robot

Reported, not scoredneither measures how well the robot works

Five-year cost$4,100

Upper range for consumer robot mowers and, unusually, the running cost rather than the purchase is what puts it there. $2,999 at MSRP, roughly $460 of blade cartridges across the four years after the first at the record's own $80 to $150 figure, two track tension services at the record's own $150 to $250 labor figure, and four years of 4G service. That last item is the assumption a reader should see: Lymow includes the SIM free for year one and does not publish what it costs after, so the figure above carries a category-typical estimate for years two through five on a connection the machine holds whenever it runs. No boundary wire and no separate base station, since the RTK antenna and mounting hardware ship in the box.

Common questions

What people actually ask.

6 answered

OperationDo I need to bury a perimeter wire for the Lymow One Plus?

No. The Lymow One Plus uses RTK positioning and virtual boundaries via the companion app. A charged docking station marks the home point; no wire burial required. You can adjust no-mow zones via the app at any time.

OperationWhat happens if RTK signal degrades (cloudy weather or nearby tall buildings)?

Lymow rates RTK accuracy at centimeter level under clear sky. Behavior when the fix degrades is not documented; the mower carries AI Vision and five ultrasonic sensors for obstacle avoidance, but Lymow publishes no fallback positioning specification.

OperationWhat is the Lymow One Plus's maximum slope rating?

Lymow rates the tracked drive at 100 percent grade, which is 45 degrees. PCWorld’s reviewer reports reliable performance around 30 degrees in real use. Test your steepest section before leaving the mower to run unattended.

CompatibilityDoes the Lymow One Plus require a subscription for app control or autonomy?

Lymow does not gate core autonomy behind a subscription. The mower ships with a 4G SIM, free for the first year; terms after that first year are not published.

OperationHow often do I replace the cutting blades?

Lymow publishes no blade-wear interval. The deck runs two SK5 tool-steel discs; replace worn blades rather than sharpening them, because grinding removes the safety coating and invites breakage on a machine running unattended at up to 6,000 rpm.

OperationCan I move the Lymow One Plus between two properties (a primary and seasonal yard)?

Dock relocation and remapping are supported in the app. Moving the mower between yards means re-running boundary setup each time; the RTK antenna and its mounting hardware ship with the machine, so there is no per-site hardware to buy.
