I ate the comment after a month of use and remove the stars. Everything is cool, but the power is absolutely not enough. The dog's hair does not clean well, the brush it in, scrolls it and spits it back out. Cat litter (a small granule, like coarse sand) in only if a pipe is placed perpendicularly on top, but it immediately falls back. After turning off the vacuum cleaner, some of the debris is poured back. It's a pity, it was very convenient at first, I was glad that cleaning was easier, but in fact the vacuum cleaner does not cope well with the main function.
