I think you dilute the Adam's product 3:1 when used in the machine. You can also use Meg's APC/APC+ at 10:1. No clue how many ounces the actual tank holds, though.
Great thread thanks guys. I picked up the "auto" version from Canadian Tire last weekend and look forward to trying it our very soon. Understanding you get what you pay for in this world I think this will be just what I need - not doing any commercial work... Thanks again.
I have one, and to me it does leave a little to be desired in the suction department. You can always follow with a wet vac. I use my Little Green Machine http://cleanthiscarpet.com/bissell-little-green-proheat-machine-small-and-cheap quite a bit. I only use distilled water in it though. All chemicals are sprayed directly onto the carpet from a spray bottle.
