So officially, Roborock hasn't sent out an update yet to do this. This is just a sad workaround so that you can use your vacuum upstairs without losing your downstairs map and its no-go zones, etc.
That said, you won't be able to save the map of the upstairs using this method, meaning you can't use no-go zones for your upstairs. But if you just want it cleaned and don't need that feature on the 2nd floor, then use this guy from reddits method. Essentially you turn off map saving mode and delete the existing map (you will still have your 2 copies of your normal map backed up). Let the vacuum clean the upstairs, then carry it downstairs and reactive your saved map.

Hi,
Thanks for reaching out.
As we mentioned earlier, we have forwarded this request to our tech team and will push them to add this feature in the future asap.
