Good help, wife is happy. Collect small debris, animal hair is the most. Does not divide the apartment into zones. Sending the vacuum cleaner to clean the kitchen will not work, you will have to take it there and close it. Wi-Fi 2.4GHz, 5 does not catch, in order to use a smartphone as a remote control, you have to switch between networks. Well, as many wrote here, a weak battery. The declared 120 minutes does not pull. For 18 minutes of dry cleaning in turbo mode in one room, it sits down by 41%. That is, the battery lasts a maximum of 50 minutes. There is not enough to clean the room, corridor and kitchen. Very bad, especially considering that it takes a long time to charge.
