This is our first robot vacuum cleaner, on the advice of friends, there is nothing to compare with. Purchased in addition to existing wireless. Low score - for the working application and the dampness of the product. Had I known, I wouldn't have taken it. Cleaning - qualitatively, for this I increased the score. First, I collected half a tray for a week, then a third. Now - a little bit. You can clean the bag after 2 days. Below are the instructions for connecting (for the summer of 2022; maybe everything has already gotten better). I will write only what is important! The rest is described in a good review (here on the market) and on the Internet. EVERYTHING matters: - WiFi - only 2.4 GHz. - the name of the Wi-Fi network - ONLY LATIN LETTERS and numbers (thanks to the "review"! It helped a lot, it was not indicated anywhere else!). - Important! - the first connection should be from Android (better, Chinese, take it from a friend for a while, if not. It will normally register the device in the Xiaomi cloud [and in the application], and then you can log in under the same account, but from the iPhone and everything will work I tried for a long time from the application for iOS, I went through all the steps, but the device did not appear in the cloud [the application only communicates with the vacuum cleaner through the cloud]). - region MANDATORY - CHINA (or "Continental China" for iOS; this is a completely different server and different settings - everything is different in the application!). If you don’t know even one damn thing, then you simply don’t understand what is going wrong. Dudes in the garage filed a script on constants 🙈. At least the sellers have collected instructions for their buyers . Finally - try to connect the application before the first use, you can pass if you don't have enough strength :) PS. The absence of a wet cleaning function is a plus. Fewer points of failure, and well, he will drive you around the floors with a dirty little rag, smear it - do you need it?
