On a segmented carpet, the automatic surface type detection function fails, turns on in dark areas, and turns off in light areas. Although in comparison with cheaper models, which generally define dark areas as an abyss and go around, this model shows itself quite worthy. Some pros: It performs its main functions perfectly. Problems with navigation, absorption are not observed. The tank hasn't leaked yet. The noise level does not raise questions, similar to a conventional vacuum cleaner. Has some cons Own application, different from Mi home, which may be a minus for someone. There are no complaints about the application itself. There is no herringbone movement function in the washing mode, which reduces the quality of this very washing. It is not clear why this feature has not yet been added, given that this is solved at the program level. Similar models from other manufacturers have this feature.
