Hi Kevin, I don't know where you are coming from about using microfiber pads for cleaning riven type floors, as I did not mention anything about using microfiber pads, I did recommend using microcleaning pads which are about 40 times more effective than microfiber for deep cleaning of hard floors, and are even more effective than cylindrical type brush machines, I can say this from experience as I have sold many cylindrical type brush machines over the years, and again from having over 30 years experience in cleaning hard floors there is nothing that will come near the power of microcleaning technology for deep cleaning hard floors.
