When I clean with cotton pads the amount of dirt removed pales in comparison to when I used 16x16 microfiber pads. What gives? I know the cotton pads being thicker have the promise of being more efficient on uneven subfloors but in general the microfiber works better and is cheaper and easier to wash.
That's interesting to hear. You must be describing your experiences with those thin, square, yellow microfiber pads, several of which I received when I bought my most recent steam vapor machine. I'll have to try using them in place of the more customary round white terrycloth pads and see if I notice the same result as you. One source of microfiber bonnets is www.swedeclean.com. They are round and 19" in diameter.
