The reasons why the dust collection time of the Xiaomi Robot Vacuum H40 is longer are as follows:
1. When the auto-empty station detects that the dust collection port or air duct is not smooth, the dust collection time can be prolonged. Please clean the dust collection port or air duct in time;
2. After the auto-empty station has been used for a period of time, it can prolong the dust collection time to maintain stable operation, which is normal;
3. Dust collection or adjustment of dust collection frequency will also affect the automatic dust collection function;
4. Check whether the disposable bag is not installed or not properly installed. An improperly installed or missing dust bag can cause dust to leak or block airflow, leading to longer dust collection times and reduced efficiency.
