6. Troubleshooting
If you encounter issues with your Ultenic U18 Pro, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Vacuum does not turn on | Battery not charged or improperly installed. | Ensure battery is fully charged and correctly inserted. Check power adapter connection. |
| Low suction power | Dustbin full, filters clogged, or blockage in the hose/brush. | Empty dustbin. Clean or replace filters. Check for and remove any blockages. |
| Brush roll not spinning | Hair/debris tangled in brush, or brush motor issue. | Clean brush roll of any obstructions. If problem persists, contact support. |
| Short runtime | Battery not fully charged, or operating in high power mode. | Ensure battery is fully charged. Use appropriate power mode for the task. Battery life naturally degrades over time. |
| Unusual noise | Blockage, loose part, or motor issue. | Check for blockages in the nozzle, tube, or brush head. Ensure all parts are securely assembled. If noise persists, discontinue use and contact support. |
