I have the vacuum cleaner now been just over a year in operation. The vacuum cleaner is with me always inserted in the charging station - so far I have seen no change in the battery. The suction power is perfectly fine to suck dust or hair from the floor - with greater crumbling but it is already problematic. For example, glass splinters from the ground absorb so reliable - that I do not trust the cleaner not to. Otherwise, the vacuum cleaner is super handy; you notice immediately when the suction performance drops and you have to clean the tank or filter. As Handstaubsauger I always use the essay, which focuses the undertow something - otherwise remain possibly larger crumbs 2 cm below the nozzle. For my purposes, the vacuum cleaner is enough, because I simply more often times short by eye because of the mobility than before, and the apartment is animal and shoe free. The 60m² one creates loose with a load, it even goes even for the stairwell. Comparable to a 1800W AEG vacuum cleaner cable is long but not. Well, still, the station where you can put away the vacuum cleaner well including the small parts.. Not so good: when you take out the hand-held vacuum cleaner of the rest of the remains barely stand still ajar on its own.
