Dear Boshravie,
I would suggest that you post this question in the 'carpet cleaning issues' forum on this site. I am sure if you fill in your profile (at least your first name and area that you operate in) that you will be bombarded with replies.
I am also looking at the benefits of the CFR system, and my only concern at the moment is when you have something suspended in the water such as urine or other not so nice substance, how one deals with it
Hopefully my question will be answered when I am down at Amtech on their spot and stain course which I believe is on the 18th of November.
Good luck on the forum
Regards
Eddie
