We sincerely apologize for any inconvenience caused.To address the issue, please follow these troubleshooting steps:
### Loud Operation
**Check Suction Settings:**- Verify if the suction is set to high in the app. Higher suction levels will result in increased noise.
**Carpet Boost Mode:**- If carpet boost mode is enabled, the robot will automatically increase suction when it detects a carpet, leading to louder operation.### Abnormal Noise During Operation
**Initial Check:**- Remove the side brush, main brush cover, main brush, and mop pad holder.- Start the cleaning process without these parts.
2. **If Noise Disappears:
**Reinstall Side Brush:**- Start the robot and check for abnormal noise.- If noise persists, check if the side brush is deformed or tangled.
**Main Brush Cover and Floor:** - If the side brush works normally, friction between the main brush cover’s rubber strip and the floor may cause noise. Continue using it a few times to observe.
**Reinstall Main Brush:**- Check whether both ends of the main brush are tangled.- Ensure the main brush cover is properly installed on all four sides.
3. **If Noise Persists:**
**Main Wheels:**- Turn off the power, press down on both sides of the main wheels, and slide them to check for smooth rotation and proper rebound.- Clean any foreign objects if found.
**Universal Wheel:**- Ensure smooth rotation by cleaning if necessary.
**Filter Element:**- If the filter element was washed with water, ensure it is completely dry before use. Wet filters can cause abnormal noise. If the problem persists, please feel free to contact us(support.na@dreame.tech) again. Thank you for your understanding.
