6. Troubleshooting
If you encounter issues while using the charging cable, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Vacuum cleaner not charging. | Loose connection, faulty power source, damaged cable, or vacuum cleaner issue. | Ensure connections are secure. Try a different USB power adapter or USB port. Inspect the cable for damage. If the cable is undamaged, consult your vacuum cleaner's manual for troubleshooting. |
| Slow charging. | Low-power USB source, background processes on vacuum, or cable degradation. | Use a higher-wattage USB power adapter. Ensure the vacuum cleaner is off during charging. Replace the cable if it appears damaged or worn. |
| Cable or vacuum cleaner gets hot during charging. | Normal operation (slight warmth), or overheating due to faulty components. | A slight warmth is normal.
