Yes, you can have it go up and down some ramps. Mine does.
Just don’t use anything that’s totally black or the cliff sensors will think it can’t travel there (I found this out by trying to hold a ramp steady with black tape and the vacuum hated it…without the black tape it worked fine).
I have a similar situation in my home (a couple of places with just 2 steps) and so I tested slope boundaries in order to figure out what kind of ramp was needed. I recorded the boundaries with some video and examples and explanations that you should find quite helpful in this post:
