How to get urine out of carpet?

He still goes to the bathroom in the house.

I have bought a “urine eliminator” spray from rug doctor. I also have a Rug doctor carpet cleaner machine. I also bought the plain carpet cleaner solution to go into the machine.

I have already cleaned the carpets once, and they still smell.

Any tips or similar situations?

Thank you!
