Unlike many competitors, it does not require any perimeter wires or buried cables, thanks to its Exact Positioning Operating System (EPOS) that uses centimeter-accurate GPS data.

Build quality is robust at 61 pounds, and the anti-theft alarm with GPS tracking adds security. The included one year of free blades and a 4-year warranty further enhance value. However, the initial price is high, and the setup requires a stable Wi-Fi connection and some time to guide the mower around the lawn for mapping.
Potential drawbacks include the lack of a built-in rain sensor, though you can adjust schedules manually. Also, with zero customer reviews at launch, real-world performance data is limited, but Husqvarna's reputation as the #1 selling robotic mower brand inspires confidence.
