I have now tested multi floor with version 1.0. Unfortunately it does not change floor/map automatically. I have tried the card for changing map “Switch to” then the card for vacuum multiple rooms and then select the rooms for e.g. second floor. It does not change floor but starts mapping a new map. I also see in the Dreame app that it stays on the last map selection. However, if I select the correct map in the Android app in advance and then run the flow, it works correctly.
Indeed, I now already have three floors with the same rooms…
I trust Mr. Pjotr to fix the problems! 
How can I select multiple rooms in the “Clean rooms” card (advanced flow)? Or is there some other solution to sweep selected rooms (without mopping)?
I wish for a “Robot water tank draining” card. I would like to activate the card via virtual (and physical) button for easy emptying of the robot when doing maintenance.
Just read my testreview… there you get all answers.
My Dreame X50 lost its way while using multi floor management. Cleaning the first floor took 220 minutes, normally 78. Restarting the cleaner solved the issue.
The best way is to select the floor in the official Dreame app. I am not sure if the Dreame cloud app caused the problem, but it started when I added the third floor in the app.
@Pjotr_Grootkop : can you make it possible to disable multifloor management? (My X50 can change the floor automatically)
My Dreame D10 Plus Gen 2 does not change maps automatically so yes there needs to be an optional feature to automatically turn multifloor on or off**.**
