Navimow vs. Mammotion Luba vs. Worx Landroid

The three wire-free mower brands people weigh against each other, judged against one quarter-acre yard with a slope on the makers' own area, slope and navigation figures.

Both the Segway Navimow H210 and the WORX Landroid Vision Cloud 1/4 Acre are rated for this lawn, and to the same figure, 10,890 sq ft. The Segway Navimow H210 is the pick on the one number that separates them: it is rated to 45% of slope where the WORX Landroid Vision Cloud 1/4 Acre stops at 30%, against the 25% bank this house has, and it is the only one of the two with a list price and an independent test to hold the maker's claims against. The Mammotion LUBA 3 AWD 3000H clears both limits by a distance, 80% of slope on all-wheel drive, and charges for it: buy that one for a hill, not for this acreage.

Two things decide the page: the slope margin, and how the mower knows where it is. All six models compared here run without a buried wire, each on its own maker's page, but they do not mean the same thing by it. Navimow's H-series and Mammotion's LUBA fuse lidar, network RTK and a camera; WORX's Vision Cloud takes its satellite correction through the charging station and reads the yard with a stereo camera; Segway's i110N leans on network RTK where the coverage reaches. The second split is what each brand will put in writing. Mammotion fills in every column this table has, Segway and WORX leave several blank, and only Navimow and Mammotion have measurements from a named tester to set beside their own claims.

Who this is for

Read on if you have narrowed it to these three brands and want the makers' own area, slope and navigation figures next to each other before you spend the money. The yard here is a quarter acre with a slope steep enough to matter and no buried wire, and every model is judged against that rather than in the abstract. If your lawn is bigger, The best robot lawn mower for a half acre with no perimeter wire puts the same question to all 15 mowers in the roster; if it is a small city lot, The best robot lawn mower for a small yard is the closer fit. And if what you want is a figure a maker never published, no page can honestly hand you one.

Against the same house

9,000 sq ftlawn area
25 %steepest slope
No wireboundary

The lawn on this page is 9,000 square feet in one mowing area, with a steepest slope of 25% and a buried boundary wire ruled out. Those are the three things all three makers state in their own terms, so those are the three the page judges on. Area nearly settles itself, but not quite: five of the six compared clear this lawn, and the two quarter-acre units are rated to the same figure. The exception is the WORX Landroid Vision AI, the half-acre model: its published lawn limit stops short of this yard, which is why the verdict table marks it as missing a limit. Slope sets the order instead, and the question is not whether a mower clears your hill on paper but how much is left over when the grass is wet and the bank is steeper than you measured. Ruling out the wire culls the wider roster rather than these six: each answers it on its own maker's page, and the fit bullets under each pick quote the line. Type your own square footage, slope and number of areas into the adjust box and those same six are judged again on your figures. It does not reach past them: the half-acre and small-yard pages above put all 15 in the roster through the same test.

Adjust to your house. Change the numbers and the picks are re-judged here, with the same rules and the same maker figures.

Our pickSegway Navimow H210

The same lawn rating as the WORX, far more slope margin

$1,799 list10,890 sq ft lawn, up to45% slope, up toRTK + lidar navigation

Segway positions it by RTK + lidar, and describes the system as lidar, network RTK and a camera working together, which is the part meant to hold a fix under trees, in narrow runs and at night. Obstacle detection runs off the same hardware and is rated down to small objects on the ground, and zones are drawn and adjusted on a map in the app. What earns it the pick against this house is the margin on the hill: the same lawn rating as the WORX Landroid Vision Cloud 1/4 Acre, a wider slope margin over it, and a lower list price than the Mammotion LUBA 3 AWD 3000H.

Living with it

Two of Navimow's services are free and one is not. Network RTK positioning stays free for the life of the mower; the Connect+ tier, which carries the cellular link, remote control and alerts, is free for the first year and renews for an annual fee after that. Blades are the other running cost: Segway's support guidance sets replacement at a fixed number of mowing hours and counts them down on a Parts Maintenance screen in the app. The warranty runs 3 years, shorter on the battery pack and adapters, with no cover on blades, and the pack is not sealed in, so an owner can swap it.

Notebookcheck's measured figures here were taken on the H206, the H2-series sibling that shares this mower's battery and lidar platform, as the table says. On that unit the tester put the noise in the middle of the field, audible but not among the loudest, and found two things the maker's page does not mention: a narrow unmowed strip along lawn edges, because the deck sits back from the chassis and there is no edge-trimming mode, and a steady draw at the dock on a full battery that counted against it on efficiency. The same review found obstacle detection stopped for a hose and a fake hedgehog but ran over a low-contrast tennis ball.

What owners and long-term reviewers report, from public threads and published reviews; not our own testing.

  • A little play in the blade disc is expected behavior on the H2 series, not a sign of a faulty unit, per Navimow's own support answer.navimow.com
  • Expect a several-inch strip of uncut grass right along borders and beds, since the H2 series has no edge-trimming feature and its deck sits back from the chassis edge.notebookcheck.net
  • Obstacle avoidance is generally reliable, but small, low-contrast objects like a tennis ball left on the lawn can get missed and run over.notebookcheck.net

What independent testers found

Notebookcheck tested the Navimow H206, the smaller H2-series sibling that shares the H210's battery and LiDAR platform; every figure in this table is from that unit, not the H210.

We do not test units ourselves. These are figures and verdicts published by named testers, with the maker’s claim beside them where the tester gave it; where a tester relays owners’ reports rather than a measurement, the row says so.

WhatFindingTester
RuntimeAbout 2 hours of continuous mowing per charge, covering roughly 300 m2 (~3,230 sq ft), tested on the Navimow H206 (the smaller H2-series sibling that shares the H210's 5.1Ah battery and LiDAR platform).Notebookcheck
Charge timeRecharged in under 2 hours, with about 100 Wh going back into the 5.1Ah battery at up to roughly 100 W.Notebookcheck
NoiseMeasured at roughly 60 dB in testing - not especially loud, but not among the quietest robot mowers either.Notebookcheck
Slope handledHandled inclines up to about 45%, which the tester called sufficient for most yards even though the H2 isn't the best climber in its class.Notebookcheck
Also notedLeft an unmowed strip roughly 10 cm (about 4 in) wide along lawn edges, because the ~45cm-wide cutting deck sits that far back from the chassis edge and the H2 has no dedicated edge-trimming feature.Notebookcheck
Also notedDrew about 13W in standby at the charging dock even with a full battery, which hurt its energy-efficiency scoring versus rivals.Notebookcheck
  • Notebookcheck called the Navimow H2 a solid, reliable robotic mower with good LiDAR-based navigation and obstacle avoidance, but said it lacks standout features and leaves wider unmowed edge strips than several competitors, some of them cheaper. Notebookcheck
  • Obstacle detection was largely reliable in testing (it consistently stopped for a garden hose and a fake hedgehog), but the H2's cameras struggled to distinguish a low-contrast tennis ball from the lawn and ran it over repeatedly. Notebookcheck

What you give up

Segway does not publish a cutting width, a cut-height range, a runtime or a noise figure for the Segway Navimow H210 on the page we captured, so several of those columns stay blank for it while Mammotion fills all of them. You are also buying a mower with no edge-trimming mode, and that gap is the one thing the tester's own verdict holds against it. If the hill is what actually worries you rather than the edges, the Mammotion LUBA 3 AWD 3000H is rated for far more of it.

Living with it

WORX is the maker here with nothing to sell you after the box: the positioning service is included for the life of the mower and no subscription tier sits behind the app's features. Maintenance is set out plainly in the manual. Inspect the blades weekly, and when they need changing, replace all the blades and their screws together as a set so the cutting disc stays balanced. The mower runs on the same PowerShare battery platform as WORX's cordless tools, and the manual's technical table gives the charge time as 80 min. For the off-season, WORX says to store the battery charged rather than flat, somewhere cool and dry.

The warranty runs 3 years from the date of purchase and excludes blades and other consumables. The manual is also the bluntest of the three about people and animals: WORX tells owners not to let the mower run unattended in automatic mode when pets, children or other people are known to be nearby, which is a stricter line than either rival puts in writing. There are no owner complaints and no tester measurements to set against any of that, because nothing independent has been published on this model that we can cite, so what you get is the maker's own record read closely, not a claim someone has checked.

What you give up

The lowest slope rating of the three. It gets over this bank on the maker's figure, but leaves the least room if the steepest part turns out worse than you measured it. WORX also publishes no runtime per charge and no noise figure, so those two columns sit blank for it, and nobody we can cite has measured either, which makes this the one pick with nothing independent to hold the maker's numbers against. If the slope is the doubt, the Mammotion LUBA 3 AWD 3000H is rated for far more of it.

Living with it

Mammotion charges nothing for the connection: the NetRTK positioning service connects with no antenna and no extra setup, is free for the life of the product, and the mower ships with years of cellular data on top. Blades get flipped partway through their life and replaced at roughly twice that, on Mammotion's own guidance, and a set from its US store is a modest recurring cost. The warranty runs 3 years and covers the battery, motors, the lidar and vision module, the positioning kit and the charging station, but only if the mower is used in the region where it was bought.

Owners report the front wheels pick up a lot of mud, and that the whole mower can be hosed down, since it is rated for it. A TechRadar reviewer had no trouble with installation, mapping, navigation or cutting, but hit occasional app connectivity drops away from home and found fine-tuning zones slower than expected. Owners also report the front wheels tearing up soft, shady turf in the zero-turn steering mode, which switching to the slower three-point turn reduces without curing; that reviewer avoided bald patches himself but knows other owners who did not. A Popular Mechanics tester found the app's joystick-style manual driving controls hard to learn next to a rival's plain arrows.

What you give up

Price, and size. It is built for acreage, and this quarter acre uses a fraction of what it is rated for, so most of what you pay for sits idle in your yard. The widest cut on the page is a bigger machine than a small lawn with tight corners wants. If your steepest slope really is what this house assumes rather than something worse, the Segway Navimow H210 does the same job for less.

Two more of the six clear this house without being picks. Segway's own i110N is rated for the same lawn as the Navimow H210 and lists for less, but its slope ceiling stops where the WORX's does, giving up the margin that decided the page. Mammotion's LUBA mini 2 AWD 1500 is rated for the same hill as the LUBA 3 AWD 3000H, but its maker's page names lidar and cameras without the network RTK correction the larger machine gets, and no tester we can cite has tested it. One more name belongs here but not to this page: the Ecovacs GOAT O1000 RTK is in the mower roster but not among the six judged above, so its limits and sources sit at Ecovacs GOAT O1000 RTK.

The first month

The first thing that happens is a map, and it rarely comes out right first time. A Popular Mechanics tester's automated run on the Mammotion still needed manual fixes afterwards, to add a section the mower had missed and to fence off exposed roots, and the whole job took the better part of an hour, slower, that tester noted, than mapping a rival mower by hand in the same yard. WORX puts its own version of that in its troubleshooting table: a second lawn area can come back unmowed when the passage joining it was mapped wrong, and the fix is to delete that passage and map it again. On the Navimow, owners who notice the blade disc moving a little are reading a normal fit rather than a fault, and Segway's support FAQ says so itself.

Setting it up

Placement, in what the makers publish, comes down to the dock. WORX pulls its RTK correction data through the charging station rather than a separate reference antenna, and its own guidance says to site that station clear of tall walls or trees that could shade it or block its signal. Segway and Mammotion ask for less groundwork: both state that the Navimow H210 and the Mammotion LUBA 3 AWD 3000H install with no perimeter wire and no reference station at all, so you charge it, open the app and let it map. That is the real difference in installation here, a dock that has to be sited well against a dock that only has to be plugged in.

Buying it right

Each brand sells several machines under nearly the same name and listings mix them. Segway's H-series is one mower in two sizes; the Navimow H210 is the smaller. Mammotion sells the LUBA 3 AWD 3000H in standard and tall cutting-height versions, so check the cut-height column. WORX's half-acre Vision AI is not the Landroid Vision Cloud 1/4 Acre, and it has no price to quote: WORX publishes no list price and no Amazon listing has passed our identity check, so its button goes to the maker's store at that day's price. Afterwards, Navimow alone charges again: Connect+ renews annually after year one, where WORX and Mammotion positioning stays free for life.

What this page can’t promise

Side by side means side by side on what the makers publish, and a published limit is a claim, not a measurement. Where a maker leaves a cell blank we leave it blank: a blank is a gap in our record, not a zero, and it is never filled in from a sibling model.

Nothing here was tested by us. Every measured figure under a pick belongs to the tester named beside it, and every complaint is an owner's, never our finding. Prices move: the Mammotion was selling under its own list price when we checked, and the Segway Navimow H210 has no Amazon listing that has passed our identity check, so its button goes to Segway's own store instead.

A slope rating is the maker's figure for dry grass on a straight run, and no table can see the wet cross-slope, the ditch at the bottom or the tree roots that decide whether a mower actually stays on your hill.

Questions people ask

Is the Navimow or the Luba better for a quarter-acre lawn?

For this house, the Navimow. Both clear the lawn and the hill on their makers' figures, and the Segway Navimow H210 does it at a lower list price with slope margin to spare. Notebookcheck called it a solid, reliable mower with good lidar navigation that lacks standout features. The Mammotion is the bigger machine and the wrong size here; it becomes the right answer when the hill or the acreage is bigger than this page assumes.

Which of the three handles the steepest hill?

By published rating, the Mammotion: 80% against 45% for the Segway Navimow H210 and 30% for the WORX Landroid Vision Cloud 1/4 Acre. A TechRadar reviewer drove the Mammotion up a slope he could not walk up unaided, using the app's manual controls. Nobody we can cite has put the WORX on a hill at all, so for it the maker's rating is the only evidence there is, which is why the narrowest margin of the three is worth more caution than the number alone suggests.

Do any of them need a boundary wire?

None of the six models compared here does, and each maker says so on its own page rather than through a sibling. Segway's line for the H-series is that you press start and the mower maps the yard itself, and its i-series page says no local antenna is needed where network RTK coverage reaches. WORX calls its setup wire-free with camera-assisted mapping. Mammotion states no wire and no base station to install. What differs is what replaces the wire: satellite correction, a camera, lidar, or all three at once.

Which one is quietest?

Of the three picked here, only Mammotion answers that on its own page: 70 dB or below for the LUBA 3 AWD 3000H. Segway states no noise level for the Navimow H210 and WORX states none for the Landroid Vision Cloud 1/4 Acre, so their cells in the noise column are blank rather than quiet. The one noise figure the Navimow has is a Notebookcheck measurement, listed under the pick with the unit it was taken on, and a measured figure and a maker's rating are not the same test anyway.

Do any of them cut right up to the edge?

None of the three claims an edge-cutting mode, and one is known not to manage it. Independent testing of the H2 series found a narrow unmowed strip left along lawn edges, because the cutting deck sits back from the chassis and there is no trimming feature to close the gap. Neither WORX nor Mammotion publishes an edge specification, and nobody we can cite has measured what either leaves, so plan on a trimmer round the boundary whichever you buy.

Is the Luba worth the extra money?

Less extra than the list prices suggest. The Amazon listing we verified has the Mammotion LUBA 3 AWD 3000H at $2,109, off a $2,799 list, while the Segway Navimow H210 has no verified listing and only its $1,799 list to go on, so the spread today is a few hundred dollars, not the thousand the list prices imply. What it buys is the hill and the all-wheel drive under it, not lawn you will use. If your steepest bank is worse than this page assumes, that is the reason to pay it.

Other houses we judged

  • Half acre, no wireThe best robot lawn mower for a half acre with no perimeter wire

    A half-acre lawn, one continuous piece, a slope you notice when you push a mower up it, and no wire you are willing to bury. Every robot mower we track, judged against that yard from the limits its own maker publishes.

  • Small yardThe best robot lawn mower for a small yard

    A small suburban lawn, a gentle grade, and a couple of beds to steer around. Almost every robot mower we track clears a yard this size, so the question stops being which one is big enough and starts being which one is worth what it costs.

  • Inground poolThe best robotic pool cleaner for an inground pool

    An inground pool of ordinary size, with walls that need scrubbing as much as the floor does. Every robotic cleaner we track, judged against it on the pool length and wall climbing the makers publish, and then on what independent testers found when they ran the machines.

  • Above-ground poolThe best robotic pool cleaner for an above-ground pool

    An above-ground pool 24 feet across, on a soft liner, with a wall you can reach over. The maker's own pool-type rating decides this page before anything else gets a say: it rules out 4 of the 13 cleaners judged here on its own.

  • Three catsThe best automatic litter box for multiple cats

    3 cats, one of them big and one of them small, and one box that has to serve all of them. Two published limits decide it: the number of cats the maker rates the box for, and the weight range its sensors were built around.

  • Pet hair, hard floorsThe best robot vacuum for pet hair on hard floors

    A shedding dog or two cats, hard floors through most of the house, low thresholds between the rooms, and a wish that the bin emptied itself. Every robot vacuum we track, judged against that house from the limits its maker publishes rather than from a lab's dust-pickup score.

  • GuideMeasure before you buy

    Every home robot is sold against a limit, and every maker calls that limit something different on its spec page. Here is how to get your own numbers first.

  • GuideApps, subscriptions and what stops working offline

    Every one of these machines still moves without the internet. What you lose is the map, the schedule, the history and, on some of them, the reason you paid extra.

  • GuideRecalls and battery safety for home robots

    Five recalls cover every robotic pool cleaner, mower, vacuum and litter box sold in the United States since 2020, and every one of them was about heat.
