First of all, let me state the Rug Doctor Spot Cleaner works exceptionally well for it's intended purpose. It is a spot cleaner. So, if you need to clean a large area (like a room) a larger machine will be easier to use and probably offer better results. For spots, like spills and pet issues (mostly my need), there is nothing near this price point that works as well.
Coming from a green machine I was cautiously optimistic about the performance and decibel level. The green thing was so loud I needed ear plugs during use. And it tended to leak around the recovery tank, requiring a towel to be placed under it during use. Better than nothing would be the most thing I could say about it.
Enter the Rug Doctor. It is packaged ready-to-go from the box, and tested for leaks before it leaves the factory - nicely done. Much quieter in operation. Quit enough that I could sit right next to it in use. Suction from the machine is great. It really leaves the area nearly dry (if you use hot water and go over it several times, like normal use of any machine). I did not have an issue with the placement of the spray trigger, but maybe that is just me and the size of my hands. The agitator brush seemed to add to the cleaning ability, easily removing some old stains in my very light carpet. I did use Resolve/Oxy as the cleaning product. Then removed it with hot water in the Rug Doctor. Haven't tried using the supplied carpet cleaning product yet, since I prefer not to leave chemicals or brighteners on my carpet. I have sensitive pets and would prefer not to have to get the machine out again from a reaction.
May be one issue and time will tell. I have only used this once so far. At the end of all the spot cleaning (several had built up after vowing not to use the green thing again), it was leaking from the recovery tank area. Did I let the tank get too full? Was it the foam? Or did I mishandle it while moving it around and dodging terrified animals? Could be any if those. It wasn't an issue for the first hour, so I might recommend emptying the recovery tank more often if you are doing a lot of spots.
Clean up is simple and straightforward. Everything comes apart easily. The hose and head are not removable for cleaning. I would recommend sucking up some clean water when you are done to clean out the head and hose. That should prevent any debris from building up and causing odors/mold. If you live in a humid climate like I do, this is an important added step.
I'll see if this lasts, but the machine is well designed and built. It's also more compact than I expected. I did buy the extended warranty, so we'll see if that is even needed in the future. Next step up from this is a commercial extractor beginning at $600+. So far, I'm delighted with the design, quality and performance of the Rug Doctor. So glad I gave it a try!
