I even got the heavy-duty traffic cleaner to work with it. We have heavy-duty stains, y'all. Three kids, three pets = messy carpet all. the. time.
Well, the rug stick hasn't worked to take out any of the stains I've used it on. None! And it leaves a sticky residue that's not pleasant to step in. And it's a pain in the butt to get the soap stuff out on the spot exactly where you want it.
Just don't buy it. It's not worth it.
