After two weeks of use, the vacuum cleaner began to lose connection with the Internet. After reconfiguration (this includes resetting to factory settings, and just reconnecting, and connecting as a new device), the connection was restored, but not for long - the maximum was enough for a day, but more often for 30 minutes. In general, now I can neither change the operating mode, nor set cleaning zone, no virtual restrictions. Yes, nothing at all, since this is only possible through the application, but since the vacuum cleaner loses connection, the application is useless! Alas and ah, the vacuum cleaner turned out to be not at all a smart device, but an ordinary badly working trash, for which I gave (you can say I threw it away) a lot of money. From today (January 5), the vacuum cleaner cannot be connected to the network (to the Internet) at all. Two days ago, with the help of the "dance with a tambourine", it connected at least for a short time, now nothing helps. Do not buy this rubbish, save your money, because in the end you will not be able to simply select any vacuum cleaner settings, even the most basic ones, such as the operating mode, scheduled cleaning, and so on!
