I read through many reviews looking for info on cleaning wool rugs. Not finding any I made a leap and purchased this machine not wanting to make a very large investment In case this did not work out. My little dog did a number soiling most of my wool rugs.
After getting familiar with the machine I tried it on an old carpet peace, seeing it worked ok I went for a 3x5 wool rug. After the first few strokes it started to clog up with the fuzz usually coming out from this type of rug. Stopped, cleaned the machine brush and around it two more times before finished.
Well let me tell you, I was so impressed! The carpet came out so beautiful, it looks new, the colors are vibrant! Having done this peace I had to completely take apart the machine, get rid of the fuzz and change the water/solution before I could do another. It is messy work (I did it on the deck) where the rugs dried in a few hours. I used worm water, not hot and the pet stain solution.
It would have cost me a ton to professionally clean all these rugs, I did get estimates. My little investment worked out great!
