I compared the Little Green Machine with the SpotBot and went for the Little Green Machine. I have found that the biggest difference between the two is that the SpotBot works without a human's help. Having said that, so far, I'm pleased with my Little Green Machine. I have cats and one is very old and has "accidents". Even if I don't catch the mess right away, and most times I don't, what with working and all, the Little Green Machine still gets out the stains and the smells. I will warn you, though, the cost of the cleaning solution is a bit expensive, but it does do a very good job. There is a small bottle of cleaning solution that comes with The Green Machine, but once that is gone, and it depends on how often you have to use it on how long it lasts, replacement solution running in the $15 to $20 range. Still, even with that expense, it does the job for which I purchased it. Next is trying it in the kitchen on the grease build up around the stove...
