This equipment should serve the short sucking in between, especially in the living room, dining room or the bathroom. Suction power, battery life and handling have initially shown quite positive. The device is fairly easy, super manoeuvrable and also sufficiently quickly recharged. Furthermore, the Bentuzung as handset is really handy especially for the car. The hopper can be easily removed as described by the manufacturer, in fact, empty and without any contact with dust and dirt. When operating as a hand vacuum cleaner, however, then noticed that at elevated suction temporarily dust clouds are blown out of the air outlets. So it does not really seem reliable (fine) dust filter, for me a great disappointment and unacceptable. Unfortunately, also the high cleaning effort for the rotating brush is quickly noticed. After each suction process, many have hair wrapped around the brush, which led to the blocking of the brush after the 2nd or 3rd suction latest (incidentally, we have no pets). Now it's not pleasant and also time consuming constantly rauszunehmen the brush to free the scissors and a hand brush of the hair and other dirt. Actually wants to maintain contact with dust and hair as short as possible and with the wireless devices have as few circumstances. After 4 weeks, and about 20 Saugvorgängen the brush then unfortunately no longer rotated. Seems to be a mechanical defect, the motor of the brush can be heard, but the brush is (even after the most thorough CLEANING). After 4 weeks I can not return the unit longer but must have it repaired. Although this is relatively straightforward to handle with Amazon, it costs a lot of time again properly packed in the thing and drag to the post office. Then it will take 2 weeks to return the unit to come back, unfortunately with the same design defects. Now I have the I'm a machine really dissatisfied, for a price of definitely is too high for this performance. Well, this time really unlucky! Addendum: We have instead a repair announced a new product after 1 week get (great performance by Amazon). Even if I somehow can hardly believe it, after 3 Saugvorgängen the brush drive was already broken again. I do not think so because of chance and see it as a confirmation that there is a fundamental design flaw of the device. Anything other than the worst rating for this device is therefore not appropriate. Now I am, however, in good spirits that I get my money back. I am thrilled with the convenience of such a lightweight cordless vacuum cleaner still, I'll look around for an alternative. Probably but a Dyson.
