Does the Spot bot work on set in urine stains?

Question

I have heard great things about the Spot Bot cleaning machine. My only worry is that most of my stains are urine stains from my Chihuahua and sometimes I don't find them in the house until they are up to a week old. (He is very sneaky) These stains are impossible to get out and I don't want to have to pay for new carpet when we move out of our apartment. Has the Spot bot worked on any old stains for anyone else??

Answer 1

We used a carpe cleaner on the carpet afet our pups were trained and they worked fine.

Answer 2

I use a carpet cleaner and use oxy deep steam pet by woolite ithink i found it at k mart or wlmart it cleans the stains good and leaves a freash scent
