Possession of him now since 2 years. He is faithful to my side, and has already survived a move. As long as one empties the collecting vessel and the filter regularly, it sucks like crazy. Not doing this, the suction power can then but much to be desired .... Unfortunately, the emptying is always a story: dusty, with no end when I pour the container into the dustbin. Sometimes it depends also fixed in the tank, and I have to pick out the stuff with your fingers. And I try to hold my breath because of dust one around the ears flies ;-) Second drawback: the much too short cable! 2 meters more would hurt anybody. I have 4 times to change the socket at a 80 m2 apartment ... that sucks. But as I said, if he is fit, he sucks really good!
