Robot lawnmower leaves uncut strips of grass and misses areas within the boundary.

Safety first: Turn OFF the mower before adjusting boundaries or blades.

• Review boundary layout: Compare your NAC boundary installation with the manual. Ensure correct distances from edges, flowerbeds, and obstacles so the mower can reach all areas.
• Increase schedule: Extend daily mowing time in the NAC programming menu so the mower has enough time to cover the entire lawn.
• Replace blades: Dull blades tear rather than cut, leaving uneven patches. Replace all blades with new NAC blades and screws.
• Check battery runtime: If the mower returns to base frequently with low charge, test or replace the battery pack to restore full runtime.

Warning: Do not move boundary wire closer to ponds, pools, or steep drops than recommended; maintain safety distances.
