I bought it as an electric broom - to quickly emble if something woke up, crashed, etc. And somehow it turned out that he didn’t have much with it that the instructions say that small fragments are prohibited. And in general, the vacuum cleaner has 3 modes of operation Eco, Norm, and Turbo, on the average Norm power is not enough to small heavy debris such as pebbles or the same small fragments into the bin, they hang somewhere in the middle of the pipe, turn off the vacuum cleaner and they fall back on the floor. You need to either take a scoop or put a short nozzle. In Turbo mode, the vacuum cleaner refuses to work longer than 10-15 seconds. writes various errors. The instructions say that when you connect a "smart" brush, the operating modes should change, this does not happen to me. Use it as a regular vacuum cleaner - I have enough battery for 80kV in Norm mode and there is no suction power. And there is also a very narrow entrance to the garbage container if you have hairballs on the floor, they very easily clog this entrance and the suction power drops even more, you have to pick it out when disembling the structure - all hands are in the mud. In general, for my purposes, the purchase did not justify itself.
