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 Eureka Boss SmartVac 4870 or one of its variants (4870, 4870MZ, 4870GZ, 4874, 4875, Boss Smart Vac), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says 61115, you're on the right track.
