I've gotten good use from this cleaner, but after reading dozens of reviews regarding the continuing problem with rusted bearings on the turbo assembly I'm beginning to wonder whether Hoover takes customer feedback seriously. There is obviously a problem with those bearings, but every time a reviewer brings it up the response is simply to ignore what the reviewer is saying and refer him for warranty service. Moreover, it appears that Hoover has no intention of addressing the problem or even acknowledging that it exists. Which is a shame, because the Power Scrub actually does a stellar job, even on white carpeting.
