Robot mower emits a burning smell or shows signs of overheating without a specific error code.

Safety first: Immediately turn OFF the mower and remove it from the lawn. Do not continue to operate if you smell burning.

Steps to check:

• Inspect underside: Look for heavy grass buildup around the blade motor and wheels. Clean thoroughly.
• Ventilation: Ensure vents on the mower housing are not blocked by dirt or debris.
• Check for visible damage: Open the housing and look for melted insulation or burnt components. Do not touch damaged parts.
• Do not reuse: If any burning smell persists or damage is visible, do not operate the mower.

When to call a technician: Overheating and burning smells require immediate professional inspection and likely replacement of affected components.
