Owner reviews
A top-tier robot mower we recommend without hesitation
Husqvarna's large-lawn flagship is built to disappear into the background of a big garden: GPS-assisted navigation, genuinely all-weather operation and the brand's trademark reliability. It's an investment, but it mows acres without complaint and barely makes a sound.
Its strongest area is coverage (100/100), followed by run time (100/100). In practice, handles huge, complex lawns.
The main caveat is navigation, where it scores 78/100. Specifically, wire install.
At €3500, it sits at the premium end of the category. For most buyers in this category, it's one of the best choices you can make.

Do I need to install a boundary wire?
Older mowers use a perimeter wire; newer wire-free models use RTK-GPS and/or vision to map the lawn — check the navigation spec above.
Can it handle slopes?
Yes, up to the max-slope rating shown. All-wheel-drive models climb the steepest inclines; standard models handle gentler grades.
Is it safe around kids and pets?
Robot mowers have lift/tilt sensors and bumper stops that halt the blades instantly, plus PIN locks and theft alarms.
How big a lawn can it mow?
See the coverage spec. Most models cover their rated area on a single charge, then return to the dock to recharge and resume.
