They supply a shampoo, but you can put whatever you like in it.
Autosmart Bio Brisk is the best.
Numatic do larger capacity Wet/Dry extractors than the George, but more for larger capacity over greater performance. Better if you do lots of large carpeted areas.
I bought a George as its perfectly big enough for cars which was my main use. I can still clean my carpets, furniture and even hard floors with it with the right attachment.
I have a steam cleaner, which is used on some hard surfaces, but for carpet and fabrics an extractor is the way to go.
