This hand vacuum cleaner is really great! We have only presented him and then we have even bought because the price-performance ratio was just great. Is great that there is a wet-dry vacuum cleaner! We suck so for example in the winter our wet window so from (with the rubber lip attachment) and it works fine! As an advantage, I still see that this battery can not be overcharged. For some devices you have to yes after some time because suckers from store away, this one you can always turn leave and has therefore always a charged Handstaubsauger at hand. The suction power is also great, 10-15 min. He is definitely the full power and that's for a hand dust Auer also enough for what else he's not even thinking. All in all, I highly recommend him!
