I also have a Vibrance as well, though I now wish it was a Premium Plus but I still love it overall. I never had a problem with those machines clogging up. In fact I actually prefer the bottom plates on them. Just like on some Panasonics, they're no seals that'd eventually disintegrate and they don't rust on the inside. My only real complaint about them is the telescoping wand that'd pop out as I'm vacuuming. But I'd disagree that a Titan or a Cirrus are better made. Cirrus uses handles that'd break easily, the Vibrance has a much sturdy handle. I also don't like that the switch on the Titan isn't on the handle like the Vibrance.
