As a result, after a year of using the vacuum cleaner, the main nozzle of the brush stopped working. Reading the forums, I saw that the problem is common, and Xiaomi did not solve the problem, it also occurs on the T30. The problem is the chafing of the wire at the fold inside the case. It is difficult to get to, but it is possible that I was tortured to disassemble. A new nozzle on alik costs about 5500r, but I did not find one in the market.
