I have one and I honestly think it's one of the best bagless uprights ever made if not the best one that's on the market right now since Bissell sold the designs, tooling, and moldings to WMJ Refurbish and rebrand it as the Workhorse Cyclonic. Very durable, reliable, and simple. Also I'm really amazed by how well it actually cleans. And honestly, it's cyclone actually works for me. The filters really don't get that dirty unless you overfill the dirt bin, same goes for Dyson or any other cyclonic bagless cleaner.
If Bissell wanted to sell their own ClearTrak or Workhorse upright, they would've just bought everything back from WMJ Refurbish. But instead they bought Sanitaire. And why would they make one where you can get a Sanitaire Quiet Clean Force bagless that works just as well but alot cheaper and better filtering than the ClearTrak?
