Initially, I was very pleased with the purchase, but after a couple of months of use, I was completely disappointed, the cleaning area is only 40 square meters, I service the vacuum cleaner regularly (I have a lot of other xiaomi equipment and wash the usual robot and humidifiers, as they say "nevpadlu" to me), but this device every time began to disappoint me more and more, and even the power loss, at medium speed even the dust and hair inside the compartment does not twist in a circle, it so badly, you have to vacuum in turbo mode, but the output is so-so, because like everyone else, the engine overheats power reset, I immediately turn it off, start the robot and spit on the whole thing, well, the cherry on the cake after the third use of the brush for sofas and mattresses, it stopped working error E03 It was necessary to take dreamy or xiaomi (the robot has been working flawlessly for 2 years already)
