Have a great day

Here is a link to the belts you need and a manual you can view which has instructions:

I would start with replacing the back hepa filter, the yellow filter on the bagless tank and the white filter beneath the intake housing. If that does not solve your problem, you have a clog in the system

depends how old it is .if its quit a few years ol i would buy a new one.some of those oplder whirlwinds ar hard to find parts for and some are just not available anymore

I am assuming that you're looking for the handle at the front of the dirt cup... Part # 28131-288N, it has been replaced by part # 74985 Dirt cup grip assembly. If you call Eureka Customer Support at 1-800-282-2886 they will be able to find you a local dealer.

If you torn the macine over, at the bottom of the sweeper you will see the belt on on side. You have to take the bottom part apart and remove the brushes to replace the belt. I hope this helps.
