We have been using the x40 with the microfibre Mobpads on oiled parquet flooring since the release, no problems or micro-scratches, I think the contact pressure is too low.

Microfibre. I have been using this robot for months and disagree that it damages oiled floors.

Thank you for your answer. I'm not worried about scratches, but the micropads remove the oil from the oiled parquet floor. There is probably nothing else left because I haven't found cotton pads anywhere yet.
