Short answer
The sticker price is only part of the story with a robot mower. Two machines that both say “1/2 acre” on the box can differ by $1,500, and the cheaper one may need a weekend of laying wire before it cuts a single blade of grass.
I run a metal and composites workshop, so tools and blades are familiar ground for me, and I look after my own lawn with EGO battery tools. Everything below comes from maker pages, university extension research and reputable reviewers, not from my own testing of these mowers.
Robot mower prices by lawn size
Lawn size is the biggest driver of price. Bigger lawns need a bigger battery, faster charging and, usually, all-wheel drive.
Mammotion’s own cost breakdown groups prices like this:
| Lawn size | Typical price range | What you usually get |
|---|---|---|
| Up to 1/4 acre (about 10,900 sq ft) | $800 to $1,500 | Small battery, narrow cut, often 2WD |
| 1/4 to 3/4 acre | $1,500 to $2,500 | Wire-free RTK or LiDAR, app mapping |
| 3/4 to 1 1/4 acres | $2,500 to $3,500 | Bigger battery, AWD, wider cut |
| 1 1/4 to 2 1/2 acres | $3,300 to $4,500 and up | Large-lawn flagships |
Those ranges match what I see on maker sites right now:
- Segway Navimow lists its US line from about $1,000 (i206 AWD, for roughly 0.15 acre) up to about $4,500 (X390), according to Navimow’s cost calculator page.
- Navimow X4 Series: the X430 and X450 are rated for 1 acre and 1.5 acres and list in the $2,000 to $3,000 range.
- Mammotion LUBA 3 AWD: the three versions cover 0.37, 0.75 and 1.25 acres and list between roughly $2,400 and $3,300.
- Worx Landroid (boundary wire): Worx’s technology page shows 1/8 to 1/2 acre models with list prices around $1,000 to $1,200, and sale prices that often drop well under $1,000.
At the very bottom, Consumer Reports gave its “smart buy” badge to the Ecovacs Goat O1000 RTK, which Hunker reported at about $700. That is unusual for a wire-free model.
My best budget robot mower guide covers the cheaper end, and the best robot mower for 1 acre guide covers bigger yards.
Prices by navigation type
The second big driver is how the mower knows where it is. I explain each system in detail in how robot lawn mowers work. Here is what each one does to the price.
| Navigation | Typical price | Setup cost and effort |
|---|---|---|
| Boundary wire | About $600 to $1,200 | Wire and stakes in the box, but hours of install or a paid installer |
| RTK-GPS with your own base station | About $1,500 to $4,000+ | Antenna on a pole or roof, power outlet, open sky |
| Network RTK (no base station) | Same as RTK, often bundled | Needs 4G or Wi-Fi coverage and a covered area |
| Camera vision | Varies widely | Little setup, works under trees, weaker on complex edges |
| LiDAR (often with vision) | Mid to high | No antenna, works in shade, newer tech |
The wired and GPS ranges come from Mammotion’s wire vs GPS guide. Keep in mind that Mammotion sells wire-free mowers, so it has a reason to make wire look like a chore. The price gap itself is easy to confirm on any retailer shelf, though.
Boundary wire: cheapest box, most labor
A wired mower ships with a spool of wire, stakes and a charging station. Husqvarna’s older Automower 115H, for example, came with about 1,476 feet of loop wire and 800 stakes in the box, according to Husqvarna’s spec page. That model is now listed as discontinued, but the kit is typical.
The hidden cost is time. Gardenista’s robot mower overview puts a wire install at about half a day. A complex yard with beds, trees and a separate back lawn can take a full weekend.
RTK-GPS: more money, less digging
RTK mowers use satellite positioning plus a correction signal, so you draw the lawn edges in an app instead of burying wire. The correction comes from either a base station in your yard or a network over the internet.
If your mower needs its own base station, it may be in the box or sold separately. Husqvarna’s Canadian site lists its EPOS RS1 reference station at about $490 CAD, and notes it’s only needed where Husqvarna Cloud coverage doesn’t reach your yard.
Network RTK: no station, but you depend on coverage
Navimow says the X4 Series works without a base station or antenna where its Network RTK covers your address, and it includes a GNSS antenna in the box for yards outside coverage. Mammotion’s iNavi service does the same for its compatible models. Both are currently free (more on that below), but you need to check coverage by address or ZIP code first.
What a robot mower costs to install
You can install almost any robot mower yourself. Paying a dealer makes sense for big, sloped or multi-zone lawns.
Wired installs cost the most to hire out, because someone has to lay hundreds of feet of wire. Eufy’s price guide puts typical professional installation at $200 to $500, up to about $800 with boundary wire, and $1,000 or more for high-end models on large properties.
Wire-free installs are cheaper to hire out because the installer mostly walks the mower around the edge and sets up the app. Navimow’s installation service article shows German dealer prices where wire-free setup costs roughly half of a cable install. Those are European numbers, but the ratio is the useful part.
Dealer-only models. Some premium mowers require a dealer visit. Husqvarna says the Automower 430X NERA with the EPOS Plug-in Kit needs a mandatory dealer garden check. Ask your dealer whether that check is priced into the mower or billed separately.
What a good install includes: a site visit, boundary setup, charging station placement, a test run and a walk-through of the app. Get the scope in writing, including any adjustments after the first few mows.
Ongoing costs: what you’ll pay every year
This is where robot mowers look good next to gas. There’s no fuel, no oil, no spark plugs and no air filter. The recurring costs are electricity, blades, a battery every few years and, sometimes, a data plan.
Electricity
It’s small. Worx estimates about $10 per year to run a Landroid. Gardenista puts total operating costs at under $25 a year. Even if your local rates are high, power is the smallest line on the bill.
Blades
Robot mowers use small razor-style blades on a spinning disc instead of one big blade. University of Florida extension notes that the blades are under 1.5 inches long, usually three to a disc, and suggests replacing them every 6 to 8 weeks during the growing season (UF/IFAS EP667).
Maker intervals vary:
| Maker | Recommended blade change |
|---|---|
| Husqvarna (main disc) | Every 3 to 6 weeks under normal conditions (Husqvarna support) |
| Husqvarna Endurance blades | Every 3 to 4 months (Husqvarna NZ) |
| Segway Navimow | Every 1 to 3 months, depending on use (Navimow blog) |
The blades themselves are cheap. A 12-pack of Navimow Blade Assembly Plus runs about $20 to $25, and Mammotion lists Endurance replacement blades at about $50 a set. Over a US mowing season of six to eight months, budget roughly $40 to $100 a year for blades.
Gravel, sand, sticks and fallen fruit wear blades faster. From the workshop side: small thin blades dull quickly by design. Don’t try to sharpen them. Swap them, and always use new screws, which Husqvarna recommends every time.
Some mowers also have a cutting disc that wears out eventually. Navimow lists replacement discs at roughly $40 to $90 depending on the series.
Boundary wire repairs
If you have a wired mower, expect to repair the wire at some point. Navimow’s wire break guide lists the usual causes: spade work, tree roots, rodents, weather and corrosion at the connectors. The wire only sits a few centimeters underground, which makes it easy to hit.
A repair is usually a coupler and a few minutes with pliers. Husqvarna’s repair steps say to trim about 2 feet back from each damaged end and join them with a waterproof coupler. Finding the break is the slow part. If you need extra wire, Husqvarna sells a 164-foot (50 m) roll for about $40 to $45.
A dedicated wire break locator saves time but costs more than the repair itself, so most owners borrow one or call a dealer only if a manual search fails.
Battery replacement
Lithium batteries wear out. Husqvarna says Automower batteries typically last 2 to 5 years. The signs are a mower that heads back to the dock more often, or stops on the lawn with an empty battery and no error.
Replacement cost scales with battery size. Navimow lists replacement packs from about $160 (2.55Ah) up to about $450 (12.8Ah, for the X4 Series). Budget accordingly if you plan to keep the mower 8 years or more.
You can stretch battery life: keep the dock in shade, clean the deck and wheels so the motors don’t drag, change blades on time, and store the mower fully charged somewhere frost-free over winter.
4G and app subscriptions
This is the cost that catches people out. Many mowers now have a built-in cellular modem for remote control, anti-theft tracking and, in some cases, network RTK corrections.
The good news for 2026: the big wire-free brands made their network RTK free.
- Segway Navimow X4: Network RTK and its data are free for the mower’s life, per Navimow. The separate Connect+ 4G service is free for 2 years on the X450 and 1 year on the X430, then about $33 a year.
- Mammotion: the iNavi network RTK service and 4G data became free for the device’s lifetime on compatible models, as Notebookcheck reported in April 2026. Mammotion’s 4G service terms also list 3 years of free data on the LUBA 3 AWD and LUBA mini 2 AWD sold after January 5, 2026, so read the terms for your exact model.
- Navimow i2 AWD: GPS tracking needs a subscription after a one-year free trial, according to Notebookcheck.
- Worx: some Landroid models use a SIM card for cloud features, which may need a data plan.
Free today doesn’t promise free forever, so check the current terms when you buy. In most cases the mower still works over Wi-Fi if you let a 4G plan lapse.
Garage, wheels and other add-ons
Optional, but common:
- Mower garage or canopy. Navimow’s X4 bundle with a garage costs about $350 more than the mower alone. A cover keeps sun and rain off the mower and dock.
- Off-road wheels for slopes and wet ground.
- Antenna mounts and extension cables if your base station needs to sit higher or farther away.
- Anti-theft extras like alarms or tracking, if not included.
A sample 5-year cost
Here’s a rough comparison for a 1/2 acre lawn. The robot figures use the ranges above; the lawn service figures come from LawnStarter, which puts a 1/4 to 1/2 acre mow at roughly $49 to $69 a visit.
| Cost item | Mid-range wire-free robot | Lawn service |
|---|---|---|
| Purchase | $1,500 to $2,500 | None |
| Install | DIY, or a few hundred dollars | None |
| Blades (5 years) | About $200 to $500 | Included |
| Electricity (5 years) | About $50 to $125 | None |
| Battery replacement | Maybe one, $150 to $450 | None |
| 4G after free period | $0 to about $35 a year | None |
| Mowing (5 years) | Included | About $1,150 to $3,060 a year by region |
LawnStarter’s annual estimates vary a lot by region because the Southeast has a much longer mowing season than the Northeast or Midwest. In a warm-season grass area like Georgia or Florida, a robot pays itself back faster than in Minnesota.
Against a lawn service, a mid-range robot usually comes out ahead inside two or three seasons. Against doing it yourself with a gas push mower, the robot rarely saves money. It saves time. I go into that trade-off in are robot lawn mowers worth it.
Two current wire-free examples
These two show what the $2,000+ tier buys in 2026. Both skip the perimeter wire and use network RTK where it’s available.

| Product | Navigation | No perimeter wire | Max area | Max slope | Cutting width | Cutting height | Runtime | Noise | Easy for beginners |
|---|---|---|---|---|---|---|---|---|---|
| Segway Navimow X430Check price | RTK + vision | Yes | 1 acres | 84% | 17" | 0.75-4 in | 110 min | 68 dB | Yes |
| Mammotion LUBA 3 AWD 3000Check price | LiDAR | Yes | 0.75 acres | 80% | - | 1.0-2.7 (high version 2.2-4.0) | 215 min | 70 dB | Yes |
The Navimow X430 covers up to 1 acre, handles slopes up to 84% (40 degrees) and cuts a 17-inch path, based on Navimow’s published specs. The LUBA 3 AWD 3000 covers about 3/4 acre, combines LiDAR, cameras and network RTK, and is rated for 80% slopes, per Mammotion. Neither is cheap, and both depend on cellular or Wi-Fi coverage for their best positioning. My best robot lawn mowers guide ranks more options.
How to keep the total cost down
- Buy for your real lawn size, not the largest you can afford. Measure the mowable area, not the lot size. Many 1/2 acre lots have under 1/4 acre of actual grass.
- Check coverage before you buy a network RTK model. If your address isn’t covered, you’ll need an antenna or base station, and maybe a mount.
- Buy wire-free if you hate yard work. A wired mower is cheaper, but a weekend of installing wire and occasional break hunting is a real cost.
- Shop the sales. Robot mowers get heavy discounts around spring and the big fall sale events. My guide on when lawn mowers go on sale covers timing.
- Change blades on schedule. Dull blades make the motor work harder, which drains the battery faster and shortens its life.
- Store it right in winter. In northern zones, bring the mower in before the first hard frost, charge it fully and keep it somewhere dry and frost-free.
FAQ
How much does a robot lawn mower cost on average?
Most current models list between about $1,000 and $3,000. Small-lawn wired models start under $1,000, and large-lawn wire-free flagships run $3,500 to $4,500 or more.
Why are wire-free robot mowers more expensive?
They carry RTK satellite receivers, cameras or LiDAR, plus more processing power and usually a 4G modem. You pay more up front but skip the wire install and wire repairs.
Do robot mowers have a monthly fee?
Not usually for mowing itself. Some charge for 4G connectivity or GPS tracking after a free period. Navimow and Mammotion currently include network RTK at no extra cost on supported models.
How much does it cost to have a robot mower installed?
Typically $200 to $500, more for wired installs on big lawns, according to eufy's price guide. Wire-free models cost less to install because there's no cable to lay.
How often do robot mower blades need replacing?
Every 1 to 3 months during the growing season for most models. Husqvarna's standard blades need changing every 3 to 6 weeks; its Endurance blades last 3 to 4 months.
How long does a robot mower battery last?
Two to five years, according to Husqvarna. Replacement packs cost roughly $150 to $450 depending on size.
How much electricity does a robot mower use?
Very little. Worx estimates about $10 a year, and most estimates land under $25 a year.
Is a cheap robot mower worth buying?
For a small, simple, flat lawn, yes. Cheaper models are often wired, have narrower cuts and fewer sensors, and struggle on slopes or complex layouts.
Do I need an RTK base station?
Only if your RTK mower relies on one and your address isn't covered by the maker's network RTK. Some mowers include the station, others sell it separately.
How long do robot lawn mowers last?
Eufy estimates 8 to 10 years for the mower itself, with a few battery replacements along the way. That is a maker estimate, so treat it as a best case.
