I got myself a new Roborock 8S Pro Ultra robot vacuum cleaner and as the base station requires dust bags which are not yet readily available, i was thinking for the meanwhile, s-bags would be good alternative for the time being.

Adapter works quite well. Just small modification to the s-bag is needed to make it fit and remove easier. (cut the bottom part of the blue part and remove the “closing” system.)

For now this design requires a o-ring ~42mm outer diameter 3.5mm thickness.

Optionally there is version for 3D printed seal + seal. (This version is untested, but should work.)

Best of all, no modifications for the base station required.

Seems to be fine to print with PLA.

(I take no responsibility if you break your base station or any other issues that could arise from using the adapter. Print and use with your own risk.)
