Input:
I am preparing to order the pet windtunnel.  The vacuum was paired with these belts as items ordered together.  I decided to check the part number first and found that, according to the video manual, these are the WRONG belts.  The correct belt part number is 562289001.  I'm thankful that I won't be stuck with useless belts and hope this helps others......... and Amazon to correct the problem.
