Cleaner for the H2O Steam Cleaner?

I own an H2O steam cleaner and want to continue using it for cleaning my carpets, but the carpet cleaning liquid that came with the machine is now all used up. I do not want to deal with this company and wonder what I can use to replace this concentrated cleaner that was mixed with water and came out in the steam leaving no soapy residue. As I am in Canada, I have to rely on Canadian retailers. I tried the Canadian Tire store, and they only have products that foam-up.
