The device provides for several months now without complaint his service and does what I expect. Take time to absorb a few crumbs or lint is done fast, because now no longer needs to phase out the "Battleship" :-) The allegations, it would be constructed and delicate parts could break off, I can not understand. I find all the pieces quite robust and you'd have to go quite rude to works to cancel anything. The double filter and the "dedusting" before emptying I find great. Caution is advised in the charging station. With noticed that they from time to time to load, which would ruin the battery pretty quickly. The storage in the thing is quite comfortable and enticing, but I would advise you to take out the vacuum cleaner when it is full and use again only when it is empty. Again, since it reacts very exemplary and turns off when the battery is too weak, so that it is discharged too deeply. It would be ideal if you could easily replace the battery pack. Some like the electric screwdriver. As you can quite simply order a replacement / spare battery. This should be mandatory, but that belongs in another forum :-)
