Pleasantly surprised by the quality, in comparison with my manual dyson of the first version - heaven and earth, in favor of xiaomi. The power is very high, while even in the maximum of the three modes it is quieter than the old Dyson in a similar turbo mode. Ergonomics, access to filters, the ability to wash the cyclone, filters and the bowl itself are very well thought out. Informative display, great battery life. The main active brush is noisy, but tolerable. It can be seen that the noise is created by the comb for removing hair and threads when in contact with the villi on the brush.
