Robot mower leaves clumps of grass and the lawn looks messy after mowing.

Safety first: Turn OFF the mower and wear gloves. Keep the mower stable before cleaning underneath.

• Sharpen by replacement: Replace dull or nicked blades with new Cedrus blades to restore clean cutting.
• Adjust cutting height: Raise the deck and mow more frequently so each cut removes less grass.
• Dry conditions: Avoid mowing when grass is very wet, as clippings tend to clump and stick.
• Clean underside: Scrape off built‑up grass from the underside of the deck using a plastic scraper. Do not use metal tools that may damage the deck.
