I bought on Ali Express, which was a mistake. After 11 months, the error is "container full" and the main engine does not start. The service center is a problem to find, you can’t return it to Ali. What to do with it is not clear. Although I am sure that the problem is some little thing, you just need to know where to fix or what to replace. I would have known that it would be like this - I would have overpaid and bought it in a normal store. . I found an electronics engineer who identified the cause of the malfunction: the mosfet on the main motor board burned out. Replaced with a similar one, but under more voltage, because. Finding exactly the same turned out to be problematic. It's been a normal flight for a few months now. If the vacuum cleaner did not break, then I could say that this is one of the best purchases of my life. Let's see how long it takes.
In addition to my words, I've included some photos to help tell the story.
