I have not yet felt the suction device for too long in use, therefore only applies as I last month. It was important that the cleaner also works bagless ... and he does. It sucks everything ... the suction power is good - I'm happy. Wet I have not sucked. He is loud as hell, which is ok because it's not a home vacuum cleaner. With us, however, he finds in the house, garden and cellar application because currently is building site anywhere. The only one that has a little disappointed me was that there are no brushes or similar attachments were there. Even the normal attachment is not particularly good, but totally ok for the price. One should not expect to get this money the 300 Kärcher variant! I am very satisfied with the purchase, the device would also like it is recommend ... and buy again.
