I was very skeptical whether such a thing which is good-but as I got home a little Krümmelmonster what I thought, anything is better than to suck after every meal or to sweep. Expected I have one thing that if you take moves over a crumb 2-3 to also receives. I get the best domestic help can be bought. The Leifheit takes everything at 1st time about driving on. Even on carpet-absolute purity. Clear at edges, eg along a kitchenette he is struggling because he has no right at the front nozzle. I would recommend the Leifheit anyone who has children or pets or even much crumbles ;-) It is so pleasant that you no longer have to be careful that someone trips over the cord. He funrktioniert yes with a battery that holds 3-4 days with me and I suck several times a day for dining area, the kitchen and the huge large play mat of my sons. Already have a 2nd order for my mother. Conclusion abolute buy recommendation.
