Manufacturer has squandered the chance ...

... To build perhaps the best battery operated vacuum cleaner of all time. The first impressions of the device are good. Very good workmanship, quality materials and a sophisticated filter system. In addition, adequate accessories and a chic charger. Cleaning very painless, as can be the light metal filter completely disassembled. The operating noise is not (but could be even quieter) too loud and the battery lasts about 10-12 days with daily one minute suck. Then you can continue even eyes Ettlich minutes, but the performance can be very strong for.
The weaknesses of the sucker are, firstly, the use of NiMH batteries, instead of a Li-Io, which would not lose its charge of themselves. In addition, an exchange which is not provided. The description is: Disposal of batteries the connecting cables are to be cut. Since NiMHs usually have a lifespan of 2-3 years, this means that you may kloppen a high quality vacuum cleaner in the bin after this time. :-(
Second, the device blows actually polluting the air at an angle of 30 ° towards the front. If you come close to a wall the suction material is swirled. That's why I stuck up my back two flaps that prevent.
I keep the device ultimately only to continue using the basket type filter in another Akkusauger later hoping. Then a small Bastelstunde. :-))

Update 17 months later:
because the collector is very large, you have to empty once every six months times the thing. even though he is very busy - the suction performance thanks to the filter structure never after. Meanwhile, a slight deterioration of the battery spühren is (often overloaded). not due to frequent load, but because of that, these NiMH batteries are good less than Li-Io - which I already described above. Charging time is 16 hours! and you get no signal if already full enough. He invites and invites and invites. the charging indicator light goes out anyway never.
have used it sometimes used to clean the car. thanks to the extremely long cable with connection to the cigarette lighter this way is awesome.
