I've had my machine for a couple of months now. I purchased it bec. I was looking for a handier cleaning tool for the hair balls that my cats "present" to us. What I found was that I needed to do a lot of pre-cleaning, otherwise the machine spreads the stain around since the brushes work in a circular pattern, just making the stain larger. Also, we have a higher pile carpet and I feel like the brushes were too rough on the 'twist' of the fibers, altering the carpet's appearance in the areas where it was used. So for us it's back to the SpotShot cleaner and the (mfr. recommended) clear dish soap/water solution. If we had low-pile carpet and wanted to clean up, say a pee spot this would be a useful tool. Also, the hand-held tool really sucks; doesn't do anything except drip the cleaning solution and make a mess.
