You fix this by doing a cycle of vacuuming first. Robots allow you to clean frequently to prevent large buildups. It's the same as if you were cleaning by hand. I have tiles as well and no dirty water marks.
i have robot running daily. it will never pick up 100% of everything. because if it would have picked up 100% there would be no need in mopping.
when i did robot shopping year ago, based on reviews and feedback it (vacuum before mopping) doesn't always work and the more polished your floor is, the worst the outcome
