What are the reasons for the decreased cleaning performance or occurrence of missed spots of the Xiaomi Robot Vacuum E5?

For your reference, here are the reasons as follows:
1. The dustbin is full and the dustbin filter is clogged. Please clean the dustbin and the filter;
2. Check if there are any foreign objects blocking the dust collection port of the main unit. Please clean the dust collection port;
3. To ensure thorough coverage, the device will clean all corners. The complex environments will increase turning and edge-cleaning actions, which will reduce cleaning efficiency;
4. If the floor is too dirty before mopping, the cleaning efficiency will be reduced. It is recommended to clean the mopping cloth midway.
