Why does the Xiaomi Robot Vacuum X20 Pro have repeated cleaning?

The Xiaomi Robot Vacuum X20 Pro appears to engage in repeated cleaning due to its navigation methods and mapping algorithms. There will be some visual repetition, however, it is not actually repeated cleaning.
For your reference, the reasons for this phenomenon are as follows:
1. The robot vacuum follows a planned path to ensure comprehensive coverage of the cleaning area. During this process, it systematically navigates and maps out the room, revisiting certain areas to ensure that no spots are missed. This can create a visual impression of repetition;
2. The robot vacuum is designed to address any missed spots or high-traffic areas that require additional attention, ensuring a thorough cleaning;
3. Despite the appearance of repetition, the robot vacuum’s actions are intended to optimize cleaning efficiency and effectiveness, rather than simply repeating the same tasks.
