In the US, the wire-free robot mowers in our price check run from $669 to $5,399 before sales tax, and a median of about $1,800. That is roughly in line with Consumer Reports, which puts the models it tested at about $800 to more than $2,500. Prices in the other three countries follow a similar pattern in their own currency. We never convert, because brands set their prices per country.

What you pay more for
The rated area is the biggest factor. In the US the median price climbs steadily with the rating.
| Rated area | Models in the US | Median price |
|---|---|---|
| Under 1,000 m² (11k sq ft) | 9 | $999 |
| 1,000 m² to 2,000 m² (11k sq ft to 22k sq ft) | 19 | $1,500 |
| 2,000 m² to 3,500 m² (22k sq ft to 38k sq ft) | 16 | $2,249 |
| 3,500 m² or more (38k sq ft+) | 11 | $2,600 |

All-wheel drive adds to the price. The median US price of an AWD model in our data is $2,399, against $1,750 for two-wheel drive. On a flat lawn you can skip it. If your lawn is steep, our guide to slopes explains why AWD is hard to avoid.
Satellite-only models are the cheapest group, at a median of $1,000 in the US, against $1,999 for satellite models with a camera and $1,999 for LiDAR models. Our guide to mowers under trees covers which type suits which lawn.
Some prices don't include everything you need. Several Husqvarna NERA models need an EPOS plug-in kit before they can work without a wire, and the fit check flags that when you set a budget.
Running costs
You'll replace blades every few weeks to few months. Husqvarna says its main disc blades typically last three to six weeks. Navimow recommends replacing blades after 80 hours of use on the H2, and Mammotion suggests every three months or 150 hours. Blade sets are cheap; Mammotion's own US store sells its Endurance replacement blades for $49.
A battery should last a few years. Husqvarna puts Automower battery life at typically two to five years, and Mammotion's US store lists replacement batteries from $149 to $209. Navimow and Mammotion give two to three years of warranty on the battery, depending on the model.
If you want GPS tracking or control away from your Wi-Fi, add a data plan. Our guide to robot mower theft lists the data plans per brand. Most mowers work without one.
When to buy
In the US, Canada and the UK, search interest in robot mowers peaks in spring. In Australia the season runs the other way, with most interest from September to December. We update prices regularly, and the date next to each price on the model pages shows when we last looked.
Common questions
What is the cheapest wire-free robot mower?
In our latest price check (Oct 26, 2026) the cheapest in the US was the Segway Navimow i105 at $669 before tax, and in the UK the Ecovacs GOAT O800 RTK at £675 including VAT. Cheap models are rated for small lawns, so check the area and slope figures before the price.
Do robot mowers have a monthly fee?
Most don't need one to mow. Some charge for mobile data after a free period, which matters for GPS tracking and remote control away from your Wi-Fi. Navimow and Mammotion sell data plans after the included period. Husqvarna says its Automower Connect service is free. Sunseeker says the NetRTK+ 4G service on the X7 Gen 2 needs a subscription after the included 24 or 60 months, at €49 a year on its global site, and doesn't say what still works without it.
