I'm thinking of getting a Dreametech L10s Ultra robot vacuum/mop, but have a few remaining concerns/questions that I'm hoping someone who owns an L10s Ultra can help me with.

Can The L10s Ultra handle small bumps? I have a "baseboard" running along the floor between rooms - there's no wall there, just a "separator" in the floor between rooms. It's about 1cm tall and has rounded corners. Will the L10s Ultra be able to move over it?

My house has 3 floors - would I need 3 base stations for the L10s Ultra to clean 3 floors? I know I'll have to pick it up and manually move it between floors, but will it vacuum/mop each floor? If it needs to dump it's dry/wet storage or runs out of battery, with only 1 base station I'll have to pick it up and move it back to the floor with the base station - but will the L10s Ultra be smart enough to know it's on another floor and not try to find it's way back to the basestation (perhaps falling down stairs in the process)?

Have you gone through the rooting process and installed Valetudo? I'd love to have mine run locally only, but the rooting process is very intimidating to me, both the part where I'd need to solder my own PCB and the part of the software process where I'd have only 160 second to do a bunch of stuff or risk bricking my $1000 device. If you've done this process, can you guess whether a noob (never soldered my own PCB, and even my soldering history in general isn't that good) might be capable?

Thanks for your input.
