Is anyone else using the microfiber pads from direct mop sales? I bought some after seeing them mentioned on this forum. They seem to work pretty well, I like that they are double sided and are reasonably priced. However the 17" seems to provide a lot more agitation than I am used to, or it is just simply harder for the pad to glide than what I am used to. I just ordered some 19" and 21" to see if more surface area would help the challenger to glide smoother. But overall I just want to make sure I don't damage anyone's carpet. I have cleaned three so far including my own, and it seems to be okay, but I would appreciated any input that other people have using this pad.
