Fascinating.............I've been extolling the virtues of the CFR machines for some time and usually got very negative feedback.
Good luck to you converts and I still maintain.........you will, or can, get as good a result as a t/m.
Don't know how the cfr is being marketted, but, when I first came accross the system, the recommended method, was ..............prespray 8-10 square metres...........aggitate with the Klanz machine.............extract with just water, preferably, warm.
Doing the above, but using dampened bonnets will also work for maintenance cleans.
