Stuart, you can use what ever you like, AMTECH push there micro splitter in preference to CFR soloutions.With the ozone machine only CFR`S O-Z CLEAN or microsplitter is compatible as the ozone in soloution will destroy anything organic which would include conventional cleaners.The ozone is activated just with a switch at the back of the machine,so if you feel the need to use for e.g a high ph cleaner you just switch it off.After cleaning if there`s a need to sanitize you empty,refill switch to ozone mode and go over the carpet again.
My market is all domestic so I rarely come across the heavy stuff.Cleaning results are a1,and I normally use a downdraft air mover to dry,approx 30 mins for aliving room.By the time I`ve cleaned the next room the last one is dry and so on.Ichose the ozone over the perfect heat model because Ifelt it had a unique selling point ,but it depends what market you`re after
By the way,I`ve yet to empty the machine in the middle of a job,just every hour stick the hose under a tap to keep the tank full [there`s only one tank] the vacume sucks the water in and off you go again.My preference in chemicals at the moment is the CFR`S because you can prespray and put some in the tank which means less time aggitating. I`d recomend the machine to anyone.
sorry for going on a bit too long
