Hello...had the same problem in an old building (each room at a different height)...sometimes over...sometimes not...I have now installed small ramps and placed a small blocking surface on the left or right,,,,Functions tiptop now

We are very satisfied with the Freo. Everything runs perfectly. However, I have to admit that we have virtually no thresholds. So: barrier-free.
Mopping in freo mode is perfect. Our Dyson is better at vacuuming - but it's enough. If the furniture is too complicated (cantilever chairs with steel tubes) or there are too many pieces of furniture on the floor, it can get confused. But all in all: very good for me.

We also have one of those Freo things. Honestly, I think these things are just stupid. You can buy any other brand and it will be better than these things.
