Seems straight forward to me, prespray, agitate, rinse = chemical down, chemical thrashed about, chemical extracted, if done properly there should be very little chemical left in the carpet as its lifted and diluted by the rinse from the wand.
I don't really keep an eye on what percentage of water I recover compared to how many litres go down but next week, for one week only, in true time limited special offer style I will attempt to be bothered enough to measure it at both ends to see if I can gauge an accurate percentage of what is left behind, that's if all the jobs I've got booked don't hear about new m3 schnitzer turbo sri evo7 and cancel me in a fit of eco friendliness (if they do I'll see if I can get some work valeting all their 4x4's
), oops, there I go again
