Uneven ground is primarily a traction and chassis problem. A mower can have excellent mapping and still fail if it loses grip, bottoms out, or digs into soft turf while turning.

  • Large-yard variants cost materially more

Drive system is the first filter

For rough ground, AWD or 4WD deserves more weight than app polish. More driven wheels can help the mower maintain traction over ruts and transitions.

GOKO and Sunseeker target the hardest terrain in this group

GOKO positions the M6 around true 4WD and rough terrain, while Sunseeker pairs the X7 with all-wheel drive and a high published slope rating.

Repair the worst lawn defects anyway

Robot mowers work best on predictable surfaces. Deep holes, exposed roots, drainage ruts, and loose edges can create repeated failures no matter how capable the drive system is.

How we research robot mowers

We normalize manufacturer specifications around the buying constraints that actually change the decision: recommended mowing area, navigation architecture, slope capability, cutting-height range, obstacle sensing, charging behavior, multi-zone support, warranty, parts availability, and current pricing. We give more weight to property fit than to feature count.

Prices, specifications, firmware, and configuration-driven features can change. Check the current manufacturer page and local requirements before buying or installing equipment.
