Bag fit belongs to the emptying station paired with the Qrevo robot.
What is actually verified
The records below describe the manufacturer-listed original items, including exclusions. They are not tests of unnamed third-party products. An aftermarket listing has to be checked separately against the exact model code Q Revo and the original identifier.

What to require from an aftermarket listing
Robot identity
Roborock Q Revo · Q Revo
Complete model and all suffixes, not only the brand.
Part identity
Exact published identifier or clearly labeled bundle component above.
Actual item identity and a written reference to the original; a borrowed photo is insufficient.
Scope and exclusions
Keep the exact dock and bag-list scope; charging-only or other Ultra bases are not inferred.
Written confirmation of the same generation and caveats; omitted exclusions remain unverified.
Performance
No VacPartFit physical test claimed.
Independent test evidence for filtration, pickup, noise or durability claims.
Returns
Check the current manufacturer store terms.
Check seller returns before opening or fitting the replacement.
When the cheaper pack is difficult to compare
Compare collar identity and station list before claimed bag capacity or price.
Dust bags fit the emptying station, not simply the robot name. Copy the full dock model from its label and compare the bag collar, sealing arrangement and station list on the manufacturer's page. A charging-only base does not use a self-empty dust bag. Plus, Omni, Ultra and AutoWash names can identify different stations rather than a universal bag family.
Open only the user-accessible bag compartment with the station disconnected as instructed in its manual. Seat the collar fully and confirm that the compartment closes without force. A full-bag or evacuation warning can also come from a blocked user-accessible air path or an incorrectly installed bag. Follow the station's troubleshooting instructions before ordering another component.
Decision before buying
Use the original record as the identity reference. If the seller cannot substantiate a conflicting model or part number, leave that aftermarket relationship unverified and seek a documented match. A manufacturer fit label does not establish seller authenticity or comparative product performance.
