I bought the same one and really like it. Since I keep a tank of water on my trailer it usually is very warm with the sun shining. I took a trick from Scottwax and brought the SCUM BUSTER Deluxe. I mixed up some carpet cleaner in a spray bottle, then spray on the carpet and use the SCUM BUSTER Deluxe. I use the carpet brush on the floor mats, but use the soft brush on the seats. When finished, I then use the carpet extractor for a final treatment. It works great! I post some pics on my next really dirty carpet.
