The silver striped one is rougher and better for tile, the microfiber one softer and better for wood floors. I ordered and extra set since the steam cleaner only comes with one of each. I ended up using all four.
We clean the carpets 3 or 4 times a year went to clean them and used this product for the first time I will never use this one again it is overpriced for the fact that it does not get any visible stains out at all just gets them wet. Had to use at full strength in order for the carpet to look like we had done anything. I usually use Zep and have no problems, I will be going back to Zep.
