Does what it should, namely suck. I use it mainly for the bathroom, because me the many hair (I have long hair) and nich upset every time I desire to unpack the big vacuum cleaner. Leaves on the balcony, he also absorbed without difficulty and even small needles from the carpet. If he is in the charging station (they have until now not suspended, but on the ground) lights a red light, which then turns off when it is fully charged. Have so far not tried, how long you can effectively suck with him until the power decreases, but for my hair on the bathroom floor, he was good enough and does not need to be loaded every time new. Price / performance ratio was right, so far no complaints, so full 5 stars.
