Robot Mowers Without a Perimeter Wire: 8 Picks (2026)

How much should you spend? The two cost patterns in this category are lawn size and navigation. The maker’s wire-free line quotes $799 for 0.125 acre, $999 early on the newer i2 all-wheel-drive class, and $1,599 to $1,799 once the i2 gains the LiDAR tier or the line reaches the H2. Past one acre the maker’s own labels step up again: $2,299 for 1.0 acre, $2,799 for 1.5 acres, and $4,499 for 2.5 acres. What decides the purchase is the measured lawn: a 0.2-acre lot with a $799 pick is a complete purchase, and the same $2,299 pick on that lawn is a specification you do not use. The cost that recurs is a blade cycle and a garage accessory at the maker’s own quote rather than a plan.

First: Answer These 3 Questions

1. Why does a wire-free robot mower cost more? Because the maker quotes the cost of navigation, and no perimeter wire to lay is how the price is high. A boundary-wire robot uses a coil under the lawn as its map and quotes a far lower hardware price for the same cutting deck. A wire-free one carries a positioning system on the mower itself: RTK satellite receivers, vision cameras, and in the maker’s i2 LiDAR a laser scanner, plus the app to map the lawn. That is the part you pay for in every quote here, from $799 at 0.125 acre to $4,499 at 2.5 acres, and the wire you are skipping is the one that frays with every winter.
2. What does the maker’s acreage number mean? It is the coverage the maker rates for the mower’s battery and mowing plan, and the honest answer is that the number is the top of the fit rather than the middle one. The maker’s own store titles its line by those figures: 0.125 acre on the $799 i105, 1.0 acre on the $2,299 X330, 1.5 acres on the $2,799 X350, and 2.5 acres on the $4,499 X390. A lawn inside that figure is a mower that finishes, and a lawn at or above it is a schedule that eats days. The honest way to buy is the lawn you walk with a tape, rounded down by a margin, rather than the highest figure the maker quotes.
3. Why is an all-wheel-drive robot mower a real feature? Because of what sits between the mower and the lawn: slopes, ruts and loose ground. The maker quotes all-wheel drive on the i2 AWD at $999 and on the i210 AWD bundle at $1,498.99, and those are the tiers that keep traction on a hillside and a wet spring. A two-wheel-drive class is the right fit for a flat lawn; the AWD tier is what an uneven lot needs, and its price is quoted on the maker’s store rather than as an upsell plan.
4. What is the difference between RTK and LiDAR? Different answers to the question of where the mower is. RTK satellite positioning, which each wire-free Navimow model quotes, is the strongest navigation over an open lawn where satellites see the deck. LiDAR, on the $1,599 i2 LiDAR, is the maker’s answer to canopies: a tree canopy, high fences and tall buildings shadow the satellite signal, and a laser scan of the environment is the system that keeps the mower on its map there. The honest pick is by the site: open sky makes RTK the cheaper route, and a heavy canopy is what the LiDAR tier is for.
5. Do these mowers need an app or a plan to mow? The app is the maker’s own tool and the mowing itself is a remote-free behavior: the mower cuts on its dock schedule and puts itself back. Every model here is a wire-free robotic mower from the maker’s own line, and the price quoted is a one-time figure on the store rather than a monthly plan. What the app carries is the map, the schedule and the no-mow zones, which are features the maker sets up once rather than pays for monthly. A robot mower with a subscription-gated feature set is a different product class, and none of the maker’s quotes here carry one.

5 Checks Before You Buy

Check	Target	Plain English
Lawn size	The measured acreage, not hoped for	0.125 acre at $799, 1.0 acre at $2,299, 2.5 acres at $4,499. A small lawn with a big mower is a spec you are not using.
Positioning	RTK, or LiDAR under cover	Open sky is RTK territory; tree canopies and tall fences are where the maker’s $1,599 i2 LiDAR tier earns its spec.
Slopes and ruts	All-wheel drive on uneven ground	The i2 AWD at $999 and the i210 AWD bundle at $1,498.99 quote the maker’s own two-wheel-drive-on-all-tiers pitch.
Docking	A garage or no garage	The maker’s Garage X is quoted at $349.99 and bundled options exist on the same store; the mower’s own dock is standard.
The maker’s page quotes a price	A real dollar figure	Every price here is a figure on the maker’s own store, which is what the ranking is honest about: no plans and no unquote-able tiers.
A perimeter wire	None, in this page’s line	Every model quoted here maps by wire-free positioning. A boundary-wire model from a different maker is a different product class.

8 Picks (By Acreage & Navigation Tier)

Navimow i105 – Cheapest Wire-Free

Price: $799.00 on the maker’s store, in stock, rated for 0.125 acre.
Why: It is the entry tier of the maker’s wire-free line and the cheapest robot mower quoted here, and its store title carries the exact figure that matters: 0.125 acre. For a small yard this is a complete wire-free purchase without the extra spend, and the positioning on the mower itself is RTK by the maker’s own line.
Honest take: The 0.125-acre rating is the maker’s own coverage figure, and a lawn with slopes or tree cover is exactly what its bigger siblings quote. It is a single model with no LiDAR and no all-wheel drive. Downside: Its coverage is the smallest figure in the selection, and anything larger than a small city lawn steps up to the $999 i2 AWD tier.

Navimow i2 AWD – Budget AWD Wire-Free

Price: $999.00 on the maker’s store, in stock.
Why: It is the most affordable model of the maker’s i2 class and the only sub-$1,000 AWD pick on the page: two-wheel drive on every deck, quoted on the maker’s store. The traction pitch is the one a hilly or loosened lot needs, and the wire-free mapping story carries over from the rest of the line.
Honest take: The i2 AWD tier is the maker’s newer generation, and its all-wheel drive quote is the spec the $999 price buys. Its positioning is RTK, which is the same satellite story as the rest of the wire-free class. Downside: It does not quote the LiDAR tier, so heavy tree cover is the case the $1,599 i2 LiDAR is built for, and the i105 at $799 is the cheaper pick for a smaller lawn.

Navimow i2 LiDAR – Best Navigation Under Tree Cover

Price: $1,599.00 on the maker’s store, in stock.
Why: It is the maker’s surveillance-free navigation tier: LiDAR on the mower itself, quoted on a store page titled for exactly that. A site with tree canopies, tall fences or satellite-shadowed corners is where the LiDAR tier does the work the satellite-only models cannot, and the $1,599 price is the maker’s own catalog figure.
Honest take: LiDAR is the honest pick for a shadowed yard: satellite positioning degrades under canopy, and the maker’s page titles this model for that navigation tier. Its wire-free mowing story is the same family’s, without a perimeter wire to lay. Downside: It is $1,599 rather than the $999 AWD tier, and a site with open sky gains less from the LiDAR spec than from the cheaper $999 model.

Navimow i210 AWD with Garage Bundle – Best Small-Lot Bundle

Price: $1,498.99 on the maker’s store for the i210 AWD with the Garage in the same package, rated for 0.25 acre, in stock.
Why: It pairs the maker’s AWD tier with the Garage in a single quote: 0.25 acre on a two-wheel-drive platform with a dock enclosure at $1,498.99. The bundle is the cheaper route than the pieces on their own, and the coverage figure is the maker’s own label.
Honest take: The Garage is a shelter pitch rather than a mowing feature, and a property with a shed already has one. The honest comparison is the same mower with and without the bundle on the maker’s own store. Downside: It is the bundle quote rather than the standalone mower price, and a household with a shed or covered patio already has the shelter the Garage is sold to supply.

Navimow H2 – Best Mid-Class Wire-Free

Price: $1,799.00 on the maker’s store, in stock.
Why: It is the maker’s H-line successor at $1,799.00, quoted as the standard mid-class tier of the wire-free family: a bigger i2-class deck and a positioning story on the maker’s own page. For a mid-size lawn where the i2 spec is tight but the X tier is overspend, this is the honest pick on the maker’s own store.
Honest take: The H2 is the maker’s mid-class tier rather than their LiDAR navigation tier under tree cover, and the acreage figure the maker quotes on the product page is the honest fit check. Downside: At $1,799.00 it sits above the $999 i2 AWD tier without the X class acreage, so the honest warning is a lawn size that either class could justify.

Navimow X330 – First of the One-Acre Class

Price: $2,299.00 on the maker’s store, in stock, rated for 1.0 acre.
Why: It is the maker’s first-tier X class mower, and the store title carries the exact figure: 1.0 acre. For a lawn at the one-acre mark, this is the entry purchase of the tier, with the maker’s vision-plus-RTK navigation and its own dock and scheduling story quoted on the page.
Honest take: The 1.0 acre is the maker-labeled coverage figure, and the store’s own price is a one-time purchase without a plan behind it. The X class builds on the i class with the maker’s higher-spec deck and navigation. Downside: The 1.0-acre class is a $2,299 purchase, and a lawn under 0.5 acre with the $999 AWD tier is a spec overspend for the same mowing.

Navimow X350 – For the 1.5-Acre Lot

Price: $2,799.00 on the maker’s store, in stock, rated for 1.5 acres.
Why: It is the maker’s 1.5-acre tier at $2,799.00, the second step of the X class on the maker’s own acreage labels. Its page carries the same wire-free positioning story as the rest of the X line, and the honest read is a coverage figure a half-acre above the X330 whose price is $500 up from there.
Honest take: The 1.5 acres is the maker’s own figure and the difference from the $2,299 X330 below it is coverage rather than new features. Its build pitch is the maker’s own site quote rather than a review. Downside: It is a $2,799.00 purchase for a half-acre’s width of extra coverage, so the honest warning is a lawn whose real figure is between the two tiers’ labels.

Segway Navimow X390 – Largest Coverage Pick

Price: $4,499.00 on the maker’s store, in stock, rated for 2.5 acres.
Why: It is the largest wire-free model in the selection at $4,499.00, rated by the maker for 2.5 acres. A lawn at this figure is the one where a manual mower is hours of weekly work, and a robot’s own navigation, at the maker’s quoted figure, is a purchase that pays back in time rather than in spec sheet details.
Honest take: The 2.5-acre figure is the maker’s own coverage number, and the honest comparison against the X350 and X330 is exactly how many acres your lawn measures. The maker’s page is the figure’s source rather than a plan. Downside: It is the most expensive pick here by $1,500 over the next step, and for a lawn below 1.5 acres it is the wrong tier by every figure the maker quotes.

One-Line Decision Table

Your situation	Pick this
Your measured lawn is under a quarter acre	The Navimow i105 at $799.00 for a 0.125-acre label, or the i2 AWD at $999.00 if traction on uneven ground is the priority.
Your property has slopes or ruts	An all-wheel-drive tier: the i2 AWD at $999.00, or the i210 AWD bundle at $1,498.99 if the Garage shelter is also what the site needs.
Your lot sits under mature trees	The Navimow i2 LiDAR at $1,599.00, the maker’s navigation tier for canopies and satellite shadow. Satellite-only positioning is the honest loss here.
Your lawn is about 1 acre	The Navimow X330 at $2,299.00, the first tier of the maker’s one-acre class, and the H2 at $1,799.00 if the figure is at the lower edge.
Your lawn is 1.5 to 2.5 acres	The Navimow X350 at $2,799.00 for 1.5 acres or the X390 at $4,499.00 for 2.5 acres, the maker’s quoted acreage tiers.
You want the mower hidden from the yard	The maker’s Garage X at $349.99 or a bundle with it quoted on the same store, and the honest question is whether the shed you already have does the same job.

Running Costs: What You Pay After You Buy

The purchase price is only part of the story. Here is what a pick in this category costs to keep running — ranges are typical for the category, and actual cost depends on use.

Item	What it is	How often	Typical cost
The mower	The one-time price	Once	$799.00 to $4,499.00 across the eight picks, from the maker’s own store
A garage or shelter	The optional dock	Once	The maker quotes the Garage X at $349.99 and bundles it on the same store
Blades and batteries	The mower’s consumables	Seasonally and by years	The maker’s store quotes replacement blades and batteries at $39.99 to $449.99
A perimeter wire	The cost you skip	Once, per wire class	$0 on every model here, versus the boundary-wire makers’ own kit prices
The app and maps	Features rather than a plan	No recurring fee quoted	The maker’s store quotes the app once, and no model here prices a mowing plan
Your hours	What the purchase substitutes	Weekly	A mower at these coverage figures is the honest comparison, not a smaller tier’s spec

Skip It If… (When Buying Nothing Is the Right Call)

This is the section most buying guides leave out. If any of these describe you, the honest advice is to keep your money.

1. Your lawn is under 0.1 acre. A $799 robot mower on a small patch is the honest answer, and a manual reel mower is the spec you are not buying.
2. The lot is flat, open and under 0.25 acre. The $999 AWD tier is traction you are not using, and the i105 is the coverage tier that fits.
3. Your lawn sits fully under tree canopy and you skip the LiDAR tier. Satellite positioning under canopy is the loss, and the $1,599 LiDAR tier is the pick that covers the question.
4. You want a wire-based mower because your lawn is a simple rectangle. The wire models from other makers are a different product class, and the honest spend is a manual mower.
5. You want the garage as a shelter without a lawn-size question. The Garage X at $349.99 is the maker’s own dock pitch and a mower without a bundle is the cheaper quote.
6. You are buying for a lawn whose real figure you have not measured. Every coverage label here is the maker’s own number for a measured lawn, and the honest purchase is the tape first.

FAQ

How does a wire-free robot mower know where to cut? By positioning rather than a buried wire. The maker’s pages for this line quote RTK satellite positioning on every model, with vision-camera assistance and, on the $1,599 i2 LiDAR, a laser scan of the yard. A boundary-wire robot needs a coil under the lawn and a repair every time one breaks; a wire-free one carries its map in the sky and its camera, and stores the no-mow zones in the app. The honest tradeoff is that satellite signal quality matters, which is why the maker sells a LiDAR tier at all.

What does the maker’s acreage figure actually cover? The maker’s own rating for how much lawn the model’s schedule, battery and cutting deck hold together. The titles on the maker’s own store quote them: 0.125 acre on the $799 i105, 1.0 acre on the $2,299 X330, 1.5 acres on the $2,799 X350, and 2.5 acres on the $4,499 X390. A measured lawn inside the figure is a mower that finishes its work in its schedule, and a lawn at the top of the figure is a schedule that eats days. The honest way to buy is by the measured figure rather than the maker’s largest label.

Why does AWD matter on a robot mower? Because the ground under the mower is not the same as the lawn above it. The maker quotes all-wheel drive on the i2 AWD at $999.00 and on the i210 AWD bundle at $1,498.99, and those are the traction tiers a wet spring or a sloping lot need. A two-wheel chassis with a traction problem becomes a stuck mower in mid-cut, and the maker’s own tier pitches the AWD class at exactly that ground. On a flat, dry lot it is a specification you are not using.

Does every wire-free mower need RTK and satellite signal to work? The base positioning is satellite, and the honest caveat is shadowing rather than failure. The maker quotes RTK across the line and adds vision-camera and LiDAR tiers where satellites alone underperform: tree canopies, tall fencing and building shadows are the environments the maker’s $1,599 LiDAR tier addresses. A mower is not lost without satellite; the deck keeps its schedule and returns to dock, and the mapping accuracy is what the added tiers buy.

Is the Garage worth buying? It is a shelter, and the honest framing is what your yard already owns. The maker quotes the Garage X at $349.99 for their line’s dock shape, and it bundles with some mowers on the same store at $1,498.99. A property with a shed or carport already has the shelter the Garage is sold to supply, and a mower whose dock is in the open needs it against weather. The spend question is the maker’s own pitch: the Garage is an accessory, not a mowing feature.

Why do the big-acreage tiers cost so much more? Because the maker quotes coverage by schedule and battery, and neither doubles cheaply. The store titles: $2,299 for 1.0 acre, $2,799 for 1.5, and $4,499 for 2.5 acres. The differences in the class are battery capacity and a mowing plan that finishes the lawn between rain windows, and the maker’s own figures are the honest comparison. A 0.3-acre lawn with a $4,499 pick is a specification you are not using, which is the reason the tiers exist.

Which brands did not make this page? The honest separations by maker quote are: the Husqvarna and Worx robotic lines quote models whose core positioning is a perimeter wire, so they are not wire-free mowers by the criterion this page uses. Mammotion, Greenworks and EGO’s lines sit behind anti-bot store pages on the maker’s own sites, so no verified dollar figure could be quoted here. Every maker whose store prices could be verified and whose line is wire-free is the Navimow line quoted on their own store, which is why eight picks come from a single maker here.

Do these mowers keep mowing when the internet is out? The dock schedule and mapping behavior do, and the app connectivity is the feature that suspends. The maker’s pages describe the mower’s schedule, its dock return and its no-mow zone map, which are on-board features; the app remote-control of the schedule is the connection feature. A mower mid-cycle with its code has both and its remote does not. The honest framing is the same one every smart device carries here: the hardware cuts, the connectivity plans.

Real Pitfalls to Avoid

1. Buying for a hoped lawn instead of a measured one. Every coverage label here is the maker’s own number, and the honest spec is what a tape measure finds.
2. Assuming wire-free means satellite-only. The maker’s own line adds a LiDAR tier at $1,599.00 for exactly the sites where satellites underperform.
3. Paying the AWD tier on a flat dry lawn. The maker quotes all-wheel drive for the traction case, and it is a spec you are not using on a flat lot.
4. Comparing the acreage labels of different makers as if they were the same figure. Each maker quotes their own coverage test, and the same label from two makers is not the same promise.
5. Buying the Garage bundle for a property that already has a shed. The Garage X at $349.99 is a shelter purchase and not a mowing feature.
