I have gone through the gallon of Spot-N-Boost that we ordered last month. The Green Genie stuff is good at removing some stains like "poof", and then others, not so good, while the SNB seems to be good at getting out what Genie doesn't.
We'll keep both, in addition to our van full of other stuff.
Did a home that had off-white Berber with lots of dog poop stains on it from the 2 little doggies. UR Out didn't seem to budge it, but they disappered when we hit them with the SNB. Didn't even get a chance to scrub yet. I love it when the spot disappears as soon as you spray the chem on it.
We liked the finished appearance, too. The Lady liked it too. So much so, that she signed up for regular 3 cleanings a year.
