Robot mower starts but stops after a few minutes without any error code, often returning to base prematurely.

Safety first: Turn OFF the mower before cleaning blades or underside.

Steps to check:

• Clean cutting disc: Remove built-up grass from the cutting disc and underside to reduce drag.
• Replace blades: Install new Worx blades and screws if the existing ones are dull or bent.
• Check charging: Verify the mower remains on the base long enough to reach full charge and that the base LED indicates normal charging.
• Battery age: If the mower is more than 2–3 seasons old and runtime has noticeably decreased, consider replacing the battery pack.

When to call a technician: If a new battery does not restore runtime, the charging circuit or current sensing on the main board may be faulty.
