Morning Dave i have a restaurant carpet to do tomorrow which has come up quite good with microsplit pre spray then envirodri sponges agitated by a host freestyle.I am going in their to try out the thermadry to see if the results are better and last longer.I have hired the machine initially to use this as a test of its(and mine) capabilitlies.The cost of thes sponges(even though i get a v.good deal) still makes the job not very profitable so if the new method works i make more money.Regards Alan
