Bought to replace Dyson V6. The new Dyson models will not add up prices for themselves, so we decided on Xiaomi and have no regrets. The first impression of cleaning is deceptive. it is much quieter than the dyson and seems to vacuum worse. But, as it turned out, vacuuming is not worse. There are three powers, we don’t use the ECO mode at all, only normal or MAX. For all the time of use, they have never been discharged "to zero", the battery is enough to clean the entire apartment.
