Im going to order a 17" dirt napper from powr-flite. What size pad does this hold? Im assuming maybe like a 15"? Also I was thinking of using green and white striped pads or should I just stick with the plain white ones they sell for this? Will trashed green be a good cleaning solution to use with this setup? Also will this do all types of carpets or would I be better off using a normal bonnet system for certain types of carpets? Thanks in advance.
