Scoring note

Reliability 8.0 (30%): still the category benchmark, with owners reporting five-plus seasons of service — but the evidence is not spotless, and battery replacement around 2.5 years plus one well-documented three-year owner who replaced motors, disc, cable and dock pull this below a perfect mark. Performance 9.0 (25%): 0.8 acre, verified 45% interior slope, 58 dB, strong in shaded and complex yards where RTK mowers fail. Usability 6.5 (20%): the boundary wire is the cost — a weekend of DIY or a paid install. Value 6.0 (15%): $2,499 MSRP plus install against wire-free rivals at half the price. Support 9.5 (10%): the best in the lineup — global dealers, long parts availability, mature Automower Connect app. Weighted total 7.8.

Known issueBattery fails around 2.5 years, typically just outside warranty; wheel motors and the cutting disc are wear items by year three boards.ie · owner thread
Take it home ifYour yard is complex, shaded or multi-zone, where GPS mowers struggle, and you value a decade-long reliability record over wire-free convenience.
Walk past it ifYou will not install a boundary wire or pay someone else to, or a battery replacement around year three would sour the purchase.
