on collecting the perfect heat cfr machine i took it home met nick holman and we did a few tests on my own carpet. glad to report was very happy with the cfr but really happy that the drimaster works with the system as though the wonder wand is a great bit of kit i have got used to my rdm and would hate to see it go. we pumped 500 psi through it and it was fine what we thought though and i hope someone with more experience will put us wise that the increase in psi from 200 to 500 did not make that much difference on the drimaster ability !!!??? DOES ANYONE THINK DIFFERENT.
