DC07 cylone not cycloning

\015 Hi .Just got a refurbished DC07 today from woot (soooo excited!!) .Put it together and started to run it…picks up beautifully…but after a few minutes running, I notices inside the canister no cyclonic action going on….still picking up lots of dirt, but the yello spinner-blade-like thing is not spinning, and my dirt is not spinning, just sitting there in a pile getting bigger and bigger……I doublre triple checked all connections to make sure everything was snapped in correctly and it was…..is this supposed to spin all the time when using or do I have a problem??thanks, michele\015 – Dyson DC07 Bagless Upright Cyclonic Vacuum
