If the suction power of the Mi Handheld Vacuum Cleaner decreases, please refer to the following troubleshooting steps:
1. Sometimes a simple restart can resolve the minor glitches, please try restarting the vacuum cleaner;
2. As the battery level is low, the suction power will decrease. Please check and charge the device for a while and use it again;
3. Check whether there’s too much debris is vacuumed or exceeds the MAX line, please clean the dust compartment in time;
4. Please check and clean whether there is any foreign matter blocked in the extension tube or the port on the vacuum cleaner;
5. Dirty or clogged filters can restrict airflow and reduce suction power. Please check whether the HEPA filter element component is blocked due to excessive dust, resulting in weak suction power. Please dry it thoroughly after cleaning;
6. The suction power will decrease if there is any damage, please check whether there is any physical damage to the motor after powering off;
7. Inspect the vacuum pipeline and connections for any leaks, cracks, or loose fittings that may be causing air leaks. Tighten connections or replace damaged pipelines as necessary.
If the above troubleshooting methods can’t resolve the issue, please contact our local official service center or your seller for further assistance. They will help you in this regard.
