in most modern product lines a defoamer is not nessisary. It's primary uses is to aid in the removal of some fiber that is foaming your machine.

Lets say you spray down a car's fabric seats. As you clean your suction hose starts to clog up with foam. By adding a bit of de-foamer to your solution tank you can keep your hose from becoming a rich lather. solution tank. This way you spray defoamer as you prep for drystroke and extraction. add just a tiny bit to your recovery tank.

If the products supplied to you make more than a light set of bubbles as you extract and dry vac. Then you need to switch. The more foam in your hose, the less suction, when suction is reduced you leave the carpet and fiber exponentially wetter.
