Thanks for all the feedback gents, sorry I have not responded sooner but just spent the last few nights crawling through a quarter mile of ducting in heat treatment plant, I appreciate the comments about pub carpets, they are covered in blacktop and I myself have wondered how this system would penetrate, break down and then remove this level of soiling. It has nothing to do with set up costs, its just we have been asked by a big blue chip about cleaning and regular maintenance of carpets and upholstry without the need to work overnight as they want quickest dry time possible with the least downtime, so my next question is would the dry fusion system be an option, a truckmount is out of the question at the moment so would something the airflex storm or jag be the best option for shortest dry times.
