Thanks for that Mark......appreciate your experience and your knowledge of this business. Have another question. I believe that by reading a lot of these threads and reading the website that this system is much better than say the HWE method. My question would be why do i not see more people using the challenger method or a similar floor machine rather than the HWE. Just curious about your take on that.

Low moisture methods have been quietly but consistently taking market share away from wet carpet cleaning over the last several years. The manufacturers of truck mounts and portables still hold the upper hand, however, in terms of their financial ability to advertise, to promote their method, to sponsor forums, to trash and disparage competing technologies, etc. Plus, culture changes slowly in many industries. Many tradespeople are conservative by nature, and wedded to the tools and techniques they have used for many years. On the other hand, there are those practitioners of HWE cleaning who have acquired low moisture machines, such as OPs and CRB (counter-rotating brush) machines, and use them in ways which improve their overall results. Examples of this are using an OP or CRB to scrub in prespray as well as fiber protections sprays.
