I have 2 of these vacuum cleaners and am totally convinced of this unit. Had previously only cyclone vacuum cleaner that even sucked when they were new. In this one it's different, I suck every day and there is enough time every 4 weeks to clean the filter, it sucks until it ad nauseam is full, I'm really excited. Self suck the car he does not stop in front of the ashtray, which always was the overkill in my other vacuum cleaners. Workmanship is good and I can confirm the negative reviews here in no way, relatively quiet, it is also my neighbor borrows it from love, because he has only ne cyclone crutch, even a will soon bring. I highly recommend him and unconditionally, a really good device
