Charger or docking station makes buzzing or humming noise

Safety first: Unplug the charger before handling. Do not open the charger casing.

• 1. Check placement: Ensure the charger is on a stable, hard surface where vibrations are not amplified.
• 2. Listen for excessive noise: A faint hum is often normal, but loud buzzing or burning smell is not.

If noise is loud or accompanied by heat or smell, stop using it and replace the Swan cordless vacuum charger.
