Robot lawnmower leaves clumps of grass and the cut looks ragged, especially in wet conditions

Safety first: Turn OFF the robot and wear gloves when handling blades.

• Replace blades: Install new genuine Ambrogio blades. Dull blades tear grass, causing ragged edges and clumping.
• Adjust cutting height: Raise the cutting height one or two steps using the Ambrogio height adjustment knob or mechanism, especially if the grass is long.
• Mow more frequently: Program shorter, more frequent mowing sessions so the robot cuts small amounts each time.
• Avoid very wet grass: If possible, schedule mowing for dry periods. Wet grass sticks under the deck and reduces blade speed; clean the underside regularly.
