The Xiaomi Robot Vacuum X20 Max will clean according to the planned path and navigate to the uncleaned areas during cleaning. 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 complete coverage of the cleaning area. It will revisit certain areas to ensure no spots are missed. This seems like repeated cleaning, but it's part of its thorough strategy;
2. During operation, the robot vacuum identifies areas that do not have been cleaned properly due to obstacles. It will navigate back to those areas to complete the cleaning process, which creates the appearance of repetition.
