@emess117 , Eileen, There could be a few reasons for your vacuum making more noise then usual, Recheck the canister/filters for proper installation and the brush head assy. also for brush/belts installed properly. I posted a couple links below that may help you trouble shoot the noise and then replace/repair the faulty part. If still under warranty contact Dyson last link below, for parts/repair/replacement/refund. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
