I have to say THANK YOU to all who have been participating in this thread. If it weren't for your loyalty to Dyson & the rave reviews, I would have given up. That said, I did a thorough cleaning (even with the tip of using a coin to unlock the floor plate). There was a ton of hair & crud under the, um, rubber band thingie. Technical term, of course.

I washed out the filter, etc. Emptied & wiped out the canister - even jabbed at the dirt in all of those teensy tiny holes with toothpicks. Did all of this yesterday and waited until today to put it all together again.
I just tested it out - kitchen & dining room were normal. The living room was THE test, though, as we have a large area rug. Set it to Carpet & proceeded to vacuum. I purposefully banged into furniture. A LOT. Because prior to this thorough cleaning, whenever I would barely bump against it, the horrid noise would start. Can I tell you, I bumped my way through the entire living room - and not the most gentle timid bumps, either - and the noise didn't happen ONCE.
What really bugs me now, though, is when I had talked to the CS woman - why the heck did she not ask if I had cleaned out the floor bar & under the rubber band thingie?? Wouldn't SHE have known to try that?? Ah well... Maybe she was new.
Anyhoo, thank you. I think I can love my vacuum again.
