Hello Dani, thank you for your question. Unfortunately, we cannot offer the V15s Detect Submarine wet floor roller for sale individually. It is not compatible with any of our other hoovers, not even with an already purchased V15. In order to intelligently switch between wet and dry cleaning, this version of the unit has been reprogrammed. Our previous software is not compatible with wet floor cleaning.
Kind regards from the Dyson Switzerland team

No

You're just trying to rip people off, it's sad.
