Wire-free robot mowers
Smart outdoor robots that give you your time back.
Independent, spec-by-spec comparisons of wire-free robotic lawn mowers. No boundary wire to bury, no guesswork - just the numbers that decide whether a mower actually fits your yard.
Why people switch
What a wire-free mower changes
The appeal is not just that the grass gets cut. It is that setup no longer means a trench around your entire yard.
No perimeter wire
Nothing to dig in, peg down, or slice through with an edger next spring. The boundary is drawn once in the app.
Hours back every month
Mowing moves off your weekend entirely. The robot works to a schedule you set and returns to its dock on its own.
Zones you can change
Add a no-go area around a new flower bed in a few taps instead of re-laying wire around it.
Slope-rated models exist
Banks and berms are where cheap robots give up. Manufacturers publish a maximum gradient, and we put that number front and center.
Quiet enough for evenings
Battery mowers run far quieter than gas. Check the published sound level if you have close neighbors or an HOA quiet window.
Everything from your phone
Schedules, cutting height, progress and error alerts live in one app. Look for models with a documented US support channel.

How big is your lawn?
Mowing capacity is the one spec that rules a model in or out. Pick your range and we will show only the mowers rated for it.
Not sure of your lawn area? Your county property record usually lists lot size - subtract the house, driveway and beds. Measuring it once with any free satellite tool also works.
Side by side
Compare wire-free robot mowers
Filter by lawn size, slope, price and navigation type. Every figure is entered by hand from an official source, and each row carries the date we last checked it.
A dash means the manufacturer does not publish that figure. We leave it blank rather than guess. Affiliate link pending means we have not been approved by that brand yet.

The trade-off, honestly
Why go wire-free?
A traditional robot mower needs a perimeter wire pegged or buried around every edge and every flower bed. Wire-free models replace that with satellite, camera or LiDAR positioning, so you map the yard from an app instead of digging a trench. It is a real convenience gain - and it comes with real conditions you should know about before you spend the money.
What wire-free gets you
- No perimeter wire to bury, peg down or repair.
- Zones, no-go areas and schedules are edited in the app, not in the ground.
- Moving a flower bed does not mean re-laying wire.
- Most models handle multiple separate lawns without a wire between them.
What to check first
- RTK satellite models need a clear sky view for the reference station.
- Dense tree cover, tall walls and narrow passages can interrupt positioning.
- Check the rated maximum slope against your steepest section, not your average.
- Confirm the warranty length and that service is actually available in the US.
These are general characteristics of the technology, not claims about any single model. Always confirm the specifics on the manufacturer's own page.

Our method
How we build these comparisons
We are a research and comparison site. We do not run a test lawn, and we will not pretend we do - here is exactly what our comparisons are based on.
-
Collect official data
Every number starts from the manufacturer's own spec sheet, manual or product page - never from a retailer listing.
-
Normalize the specs
We convert areas, slopes and runtimes into the same units so models can genuinely be compared line by line.
-
Weigh the real constraints
Navigation type, rated slope, warranty length and US support footprint carry more weight than headline features.
-
Re-check and date it
Prices move. Every model carries the date we last verified it, so you always know how fresh the figure is.
Where our numbers come from
Every figure on this site is traceable
We do not test these machines and we never pretend to. What we do is read the manufacturer's own published data, record it with the date, and show you the date next to the number.
We do not test these machines. We do check every number, and we date it.
- Manufacturer page The official product page. Never a reseller, never a marketplace listing.
- Their own structured data The price and availability they publish for search engines to read.
- Recorded with the date No estimates. If we cannot read it, the field stays blank.
- Shown dated in our table The date sits next to the number, so you can judge it yourself.
If a manufacturer does not publish a figure, the cell stays empty. We would rather show a gap than a guess.

Questions people actually ask
Frequently asked questions
Do wire-free robot mowers really work without a perimeter wire?
Yes. Instead of a buried wire they position themselves with satellite RTK, onboard cameras, LiDAR, or a combination of those. You draw the mowing boundary once in the app. The trade-off is that each technology has its own environmental requirements, which is exactly what our comparisons focus on.
How do I know which mower fits my lawn?
Start with two numbers: your total lawn area and the gradient of your steepest section. Those two rule out most of the market immediately. Our lawn-size selector and slope filter do that first pass for you.
Do you sell the mowers?
No. We do not hold stock, take payment or ship anything. Every buy button sends you to the manufacturer, who handles the sale, delivery, warranty and returns directly.
How do you make money?
Through affiliate commissions. If you buy after following one of our links, the manufacturer may pay us a percentage of the sale. It costs you nothing extra and it does not change the price you pay.
Do you test these mowers yourselves?
No, and we will not pretend otherwise. We analyze official manufacturer documentation, published specifications, warranty terms and verifiable owner feedback. Our review method page explains exactly what that covers and what it does not.
How current are the prices you show?
Every model shows the date we last checked it. Prices change often, so the figure on the manufacturer's own page is always the authoritative one - check it before you buy.
Will a wire-free mower work under heavy tree cover?
It depends entirely on the navigation technology. Satellite RTK systems need a clear view of the sky for their reference station and can lose position under a dense canopy. Camera and LiDAR systems are generally less sky-dependent. This is the single most common reason a mower disappoints its owner, so we list navigation type on every model.
