The assistant in maintaining order is excellent, I have been using it for more than a month of complaints and comments of serious breakdowns or any failures did not happen. It fully copes with its tasks 28 square meters cleans in an average of 23 minutes. Works with 2.4G Wi-Fi But does not support WPA 3, 5G does not work. I can’t single out this as a plus or minus, but I think that everyone should know that the vacuum cleaner is localized for 2022 and will not be able to work together with Chinese devices in one application.
