I can't recommend it at all. It worked fine for 3 months, but now it's not annoying at all. We've done some troubleshooting work, but it looks like this device is. Reading other reviews it seems that this is not an isolated case. It's a real shame when you're paying $300 for a vacuum that's listed as 'commercial' you should have a reasonable expectation that it will last and perform well. Unfortunately not. However, Revane was great on his return, so we'll find something else.
