They aren't bad for being a bagless machine in their price range, and they seem to last fairly well, better than Bissell's machines for sure. They're not too bad at keeping their suction either, the cyclone does OK at keeping the filter clean enough to last maybe washing every 2 weeks or so. We sell them at work, and sometimes get used ones (either abandoned repairs or people give them to us, or trade up to a Miele or Simplicity or something.) and for a bagless its a machine I really don't mind selling, I feel good enough about the quality.
