I know what you mean...the products are fantastic...I used to be a tester/advocate for them
I just use the all purpose cleaner in Pink Grapefruit to clean any pee accidents...but my area carpet is dark and so its easily hidden and the rest is hard wood floors...so as for stains I'm not sure which method product would get them out...I checked the website and I didn't see anything specifically for carpet.
But doesn't the oMop look fabulous?? I think I'm going to get it...
