- It is recommended to fully charge the vacuum cleaner's battery before its first use and after each cleaning session for optimal performance.
5. Maintenance
Proper maintenance ensures the longevity and safe operation of your adapter:
- Cleaning: Disconnect the adapter from the power outlet and the vacuum cleaner before cleaning. Wipe the adapter with a soft, dry cloth. Do not use liquid cleaners or solvents.
- Storage: Store the adapter in a cool, dry place away from direct sunlight and extreme temperatures. Avoid tightly coiling the cable to prevent damage.
- Inspection: Periodically inspect the adapter and its cable for any signs of damage, such as cuts, fraying, or bent pins. If damage is observed, discontinue use and replace the adapter.

6. Troubleshooting
If you encounter issues with your adapter, refer to the following common solutions:
- Vacuum Cleaner Not Charging:
- Ensure the adapter is securely plugged into both the wall outlet and the vacuum cleaner's charging port.
- Verify the wall outlet is functional by testing it with another device.
- Inspect the adapter cable and connector for any visible damage.
- Important Note: Rechargeable batteries have a limited lifespan (typically 1 to 3 years). If the vacuum cleaner's battery is old or faulty, it may not accept a charge, which is not an issue with the adapter.
- Adapter Feels Warm: It is normal for the adapter to become slightly warm during operation. If it becomes excessively hot or emits a burning smell, immediately unplug it and discontinue use.
