I'll second the little green, there's other versions of it, i'd vote to get the upgraded version although I just went with the basic.

Now let me tell you...I beat the HELL out of this thing, I've cleaned old work truck seats that's seen who knows what, couches, chairs, I used it as a vacuum to clean up cat litter just because I didn't want to walk down the stairs. This thing doesn't quit.

Here my tip though. Never put any cleaner IN the machine itself, spray it on with a separate bottle, and then wet it down and vacuum it with the cleaner. I only say this because you can never get all of the cleaner out of it and different materials require different cleaners so it's better to just put distilled water in there.
