How to confirm it's your model
Find the vacuum's rating plate: it's usually on the bottom or under the bag compartment lid. It shows the exact model. If it matches the Hoover WindTunnel Canister S3639 / S3670 or one of its variants (S3639, S3670, S3630, Anniversary WindTunnel Canister), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says 4010100S, you're on the right track.
How to change the bag on the Hoover WindTunnel Canister S3639 / S3670
- Unplug the vacuum and open the bag compartment lid.
- Pull the used bag out by its cardboard collar and seal it with the hygiene tab if it has one.
- Slide the new bag into the guide all the way, with the collar seated firmly on the intake.
- Unfold the bag inside the compartment so it isn't creased, then close the lid. If the lid won't close, the bag isn't seated correctly.
- Every 4 or 5 bags, check or replace the motor filter.
How often should you change the bag?
In a typical home, every 4–8 weeks. Change it sooner if the full-bag indicator turns red, suction drops, or it starts to smell. Don't wait until it's bursting: above 75% full, suction drops sharply.

Frequently asked questions
What bag does the Hoover WindTunnel Canister S3639 / S3670 take?
The Hoover WindTunnel Canister S3639 / S3670 uses Hoover Type S (WindTunnel canister) bags. The genuine part number is 4010100S (also listed as Type S). Compatible bags that list that part number or the model in the title also fit.
Do compatible bags work in the Hoover WindTunnel Canister S3639 / S3670?
Yes. Good-quality compatible bags have the same cardboard collar and are usually multi-layer microfiber, which filters as well as or better than the original paper. Pick packs with lots of reviews that list part number 4010100S.
How often should you change the bag on the Hoover WindTunnel Canister S3639 / S3670?
In a typical home, every 4–8 weeks. Change it sooner if the full-bag indicator turns red, suction drops, or it starts to smell. Don't wait until it's bursting: above 75% full, suction drops sharply.
Can I empty and reuse the Hoover WindTunnel Canister S3639 / S3670 bag?
No. Paper and microfiber bags are disposable: emptying them damages the filter pores, and fine dust goes back into the air and the motor. A new bag is cheap and protects your vacuum.
