Mike,
Can't compare it to CFR cos never used that, it does use water, but not as much as I expected and it's a lot quicker than using a standard hand tool.
We've been pre-spraying, agitating then extracting with the Drimaster set at about 50%, all the suites have been almost touch dry when finished, done draylon, brockades and a really bad tapestry suite that came up great with just one pass.
