good morning, if you would help me I would appreciate it.. I have a ORECK model 21XL bought in 2004 I'm looking for the best bag. I use it in a very dusty area. How often should I change the belt. Thank you
These bags will work. If you are look for cloth like bags then look at these https://www.ezvacuum.com/oreck-type-cc-odor-neutralizing-vacuum-bags-replaces-ccpk8of-8-pack-p-5011.html
The belts should be changed every 2-3 months if there is regular use of vacuum and when you feel that the rollers are not picking up much dirt.
