It worked properly for about a week, after a week it started to fail: 1. I didn’t react to commands through applications, I had to restart the application several times; 2. Did not do it, start cleaning in the next room, he will arrive there and immediately return, supposedly the cleaning is completed; 3. After 2 weeks, it stopped running through the application at all, writes that it is not online, you restart everything several times, zero reaction. It cleans not bad, but it is not controlled from the phone, respectively, all these additional steps in the form of building a map, etc. generally meaningless.
