Robot Vacuum cleaner for a duplex house

Hi,

I am starting to explore options of buying a robot vacuum cleaner.
I see multiple challenges if it has to be used in a duplex house.
1) Manually shifting the robot between floors
2) Can the robot support multiple layout and schedules?
3) The robot goes back to its docking station once the cleaning is done. What happens if it is on a floor where the docking station is not preset?

Is there a product which supports multiple floors?
Please share your thoughts.

Thanks,

I bought a top of the line samsung one years ago. While it came with plenty of features including the ones you mentioned, it was nothing more than a fancy bug. The cleaning was nowhere close to efficient as comparable to manual brooming. It can pick big things but the surface was still dusty. Absolutely useless if you've carpets.
Fast forward now, the device that was supposed to clean dust has been collecting dust itself somewhere.
