Maintenance
- Dual-Rotation Self-Cleaning:
After each use, place the vacuum on its charging base. Press the self-cleaning button. The brush roller will rinse thoroughly, rotating forwards and backwards to remove debris.

Figure 8: One-Press Self-Cleaning - Hot Air Drying:
Following self-cleaning, the hot air drying technology activates, drying the brush at 131°F (55°C) within 30 minutes. This prevents odors and ensures the brush is ready for the next cleaning session.

The integrated serrated brush scraper helps prevent hair from winding around the roller. For deeper cleaning or replacement, use the one-button operation to easily remove the brush roller.

Troubleshooting
If you encounter issues with your Dreame H12 Pro Plus Mix, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery; improper charging. | Ensure the device is fully charged on the charging base. Check power connection. |
| Poor cleaning performance / Low suction. | Clogged brush roller or filter; dirty water tank full; clean water tank empty. | Perform self-cleaning. Clean or replace the filter. Empty the used water tank and refill the clean water tank. |
| Unpleasant odor from brush roller. | Brush roller not properly dried. | Ensure the hot air drying function completes after self-cleaning. Manually dry if necessary. |
| Hair winding on brush roller. | Excessive hair accumulation. | Utilize the serrated brush scraper during cleaning. Remove and clean the brush roller using the one-button release. |
| Voice prompts are unclear or not working. | Volume settings; software glitch. | Check device settings for voice prompt volume. Restart the device. |
| Incorrect plug type for region. | Purchased device with incompatible plug. | Ensure you select the correct plug type (EU, UK, AU, JP) for your region during purchase. A universal adapter may be used if necessary, but ensure it is rated for the device's voltage (100-240V). |
User Tips
- For optimal performance, always ensure the clean water tank is adequately filled and the used water tank is emptied before and after each cleaning session.
- Take advantage of the 4-in-1 design: use the wet/dry function for hard floors, and easily convert to a handheld or stick vacuum with appropriate attachments for carpets, upholstery, and other surfaces.
- Regularly check and clean the brush roller and filter to maintain strong suction and prevent blockages, especially if you have pets.
- The device supports a wide voltage range (100-240V), but always verify that the plug type matches your regional electrical outlets (e.g., EU, UK, AU, JP).
