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 Shop-Vac 5–8 Gallon or one of its variants (5 Gallon, 6 Gallon, 8 Gallon, Shop-Vac 5-8 gal), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says 90661, you're on the right track.
How to change the bag on the Shop-Vac 5–8 Gallon
- Unplug the vac and release the latches to lift off the motor head.
- Remove the used bag by pulling its collar off the inner intake port and throw it away sealed.
- Push the new bag's collar onto the tank's intake port until it's secure.
- Spread the bag across the bottom of the tank and reattach the motor head.
- For picking up liquids, always remove the bag (and on many models the paper filter too).
How often should you change the bag?
It depends on what you pick up. Fine construction dust (drywall, cement, sanding) clogs it in one or two sessions; cleaning out the garage or car it can last months. The clear sign is a loss of suction.
