My personal preference is always to use a microsplitter, but it's down to choice, so whatever works for you.
A tip I would give which is especially useful on heavily soiled suites as well as more moderate levels, is to take plenty of towels. Pre-spray as usual then agitate with a folded towel pad rather than a brush. You are removing soil whilst agitating and also removing moisture. Re-spray if necessary and repeat towelling. Your extraction rinse will be easier and quicker and you are much less likely to over wet with this technique.
Safe and happy cleaning:)
