I bought it to replace the Panda X7, which tortured me with its stupidity and constantly falling off WiFi, as a result of which I could not set it up for scheduled cleaning. Therefore, all the described advantages are written precisely in opposition to this model, although they are the same for the price. So be careful, don't buy the X7, the rest of which is still on sale, even the price has not been reduced (although it is discontinued or sold to another brand LIECTROUX C30B, which costs at least half the price). Bad reviews about the above vacuum cleaners are diligently cleaned on all resources, tested on myself. At one time, I was seduced by rave reviews, "Japanese quality", etc. as a result threw 35t. and feel cheated, do not repeat my mistakes and buy really the best that is now. And Xiaomi robots in terms of intelligence, smartphone application and mapping are probably really the best on the market in their price range, I take my hat off! I also want to warn those who think that a robot vacuum cleaner will completely replace everything for them - ordinary vacuum cleaners, rags and mops, in fact it is not. The robot vacuum cleaner allows you to keep clean, provided that cleaning is done regularly, at least once a day. And in any case, you will need a regular vacuum cleaner, for deeper general cleaning, especially carpets and furniture.
