The function that is supposed to automatically recognize the surface type fails when it is applied to a carpet that is segmented, turning on in darker regions and turning off in lighter sections. Despite the fact that, when compared to less expensive models, which typically refer to dark spots as abysses and move around them, this model demonstrates that it is highly worthy. Some pros: It is excellent at the primary functions that it was designed to fulfill. It does not appear that there are any issues with navigation or absorption. The tank has not developed a leak as of now. The noise level does not create questions, similar to a typical vacuum cleaner. Below are some downsides: Own application, which is distinct from Mi home; this could be a disadvantage for some users. Regarding the application itself, there have been no negative comments. The fact that the washing mode does not have a mechanism for herringbone movement brings down the overall quality of the washing. Given that this problem can be fixed at the software level, it is unclear why this functionality has not yet been included in the product. This feature can be found in products of other manufacturers that are functionally equivalent.
