Which one do you recommend?
  • Britax
  • Rug Doctor

Why? Which is cheaper? Which is easier to use for carpets and upholstery?

I have a massively filthy acrylic Berber (easily stains) carpet and some green old couches that need a good clean. I have some spare money and have worked out its cheaper to do it myself rather then $100 for 3 room and $100 for 3 couch seats when I have 5 couch seats and 5 rooms.

I have read about using white vinegar as a rinse or something anyone have more details on this. Thank you.
