best robot lawn mower large acreage: what to check

Acreage capacity and per-charge area

Acreage capacity and per-charge area are different figures. The Husqvarna 420 iQ and the WORX WR340 list capacity up to 1 acre, while the MOVA LiDAX Ultra 3000 AWD and the HOOKII Neomow X SE list mapping up to 0.75 acre. The MOVA listing gives up to 0.25 acre per charge with automatic recharging, and the HOOKII listing gives up to 0.17 acre per charge.

Slope handling

Slope ratings differ sharply here. The MOVA listing states slopes up to 80%, the Husqvarna listing states slopes up to 45%, and the WORX listing states a 30% slope. The HOOKII listing does not state a slope rating in its bullets. Never exceed the maker maximum slope, and keep children and pets out of the yard while it mows.

Navigation and obstacle avoidance

The Husqvarna 420 iQ uses EPOS navigation with virtual zones set in an app, and onboard radar helps it avoid obstacles. The WORX WR340 uses RTK Cloud navigation with Vision AI auto mapping and no perimeter wire. The MOVA pick uses 360 degree 3D LiDAR with AI dual vision for 300+ obstacles, and the HOOKII pick uses 360 degree 3D LiDAR with AI Vision fusion for 200+ obstacle types.

Cutting height and edge cutting

The Husqvarna 420 iQ adjusts from 1 to 4 inches, the MOVA LiDAX Ultra 3000 AWD adjusts from 1.2 inches to 3.9 inches, and the HOOKII Neomow X SE adjusts from 1.18 inches to 3.35 inches. The MOVA listing also gives a 15.8 inch cutting width with 12 blades and edge cutting that leaves 1.2 inches of edge grass. The WORX listing does not state a cutting height range in its bullets.

Warranty and security features

The Husqvarna bullets state a 4-year warranty, while its spec table states a 3-Year Limited Warranty, a contradiction noted in its review. The MOVA and WORX listings state a 3-year warranty, and the HOOKII listing states a 2-year warranty. For security, the Husqvarna listing gives an anti-theft alarm with GPS tracking, the WORX listing gives GPS tracking with remote lock, the MOVA listing gives PIN locking, and the HOOKII listing gives GPS anti-theft. See the Walk-Behind and Robotic Mowers hub.

The Acre Score explained

The Acre Score weighs performance, build quality, value, safety and warranty. Performance covers acreage capacity, slope handling and navigation. Safety covers obstacle avoidance, anti-theft features and PIN locking where a listing states them. A factor the listing does not state scores zero.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
