Large-yard buyers should prioritize throughput, traction, charging strategy, and navigation robustness before app features.

Sunseeker X7 stretches furthest on paper

Sunseeker rates the X7 family for up to 3 acres and combines that with all-wheel drive. That makes it one of the first models to examine for genuinely large residential properties.

GOKO M6 targets difficult terrain

GOKO positions the M6 around steep slopes, rough terrain, true 4WD, and up to an acre per charge. It is especially interesting where traction is the bottleneck.

Hookii offers multiple acreage tiers

The Neomow X2 family scales from small-lawns variants to a 1.5-acre Pro model, which makes the platform easier to size to the property.

How we compare robot mowers

We normalize manufacturer specifications around the same buying constraints: recommended mowing area, navigation architecture, slope capability, cutting width and height, obstacle sensing, charging behavior, multi-zone support, warranty, and current selling price. We give more weight to property fit than to feature count.

Prices, specifications, and configuration-driven features can change. Check the current manufacturer page before buying.
