Can anyone recommend a good carpet shampoo ????

[Gizmonster]

I have a George Numatic carpet cleaner.
I'm after a decent carpet shampoo. It has to be non-foaming, as my machine is an extraction machine.
Can anyone recommend one ??
At the mo I'm using "Nuchem 4", but it's about to run out. Has anyone got any that they can vouch for ??
(Plz don't just send me links for carpet shampoos, I'm after 1st hand recommendations only thanks).

depends what you want to clean up. Bissell pet is okay but for "organic" spillage, I use zybax.

Just for general carpet cleaning - domestic use only.

then bissell pet is good.
