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 Dreame X40 Ultra or one of its variants (X40 Ultra Complete, X40 Pro), these bags will fit.
Tip: if you still have a used bag, check the cardboard collar. If it says X40 Ultra dust bag, you're on the right track.
How to change the bag on the Dreame X40 Ultra
- Open the top lid of the self-empty base.
- Pull the used bag out by its handle: on most bases the seal closes automatically as you remove it.
- Slide the new bag into its guide until it clicks. Without a bag the lid won't close or the app shows a warning.
- Close the lid and run an empty cycle from the app to make sure there's no error.
How often should you change the bag?
Every 30–60 days with daily use: each bag handles dozens of empty cycles. With pets, more often. The app usually alerts you when it's full.
