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

Safety first: Turn OFF the mower and keep hands away from blades.

Steps to check:

• Raise cutting height: Set the Worx mower to a higher cutting height and gradually lower over several days.
• Replace blades: Install new sharp blades to improve mulching.
• Clean deck: Remove built-up grass from the underside of the mower to improve airflow and discharge.
• Avoid wet mowing: Schedule mowing for dry periods; wet grass clumps more easily.

When to call a technician: No technician is usually required; this is typically a maintenance and usage issue.
