I find that microsplitting solutions have made my working life simpler. But like John, not easier, but certainly safer/healthier.
What works for me on all domestic carpets, regardless of soil degree or type and regardless of carpet fibre, is a Woolsafe microsplitter. For those who use a Sebo Duo for agitation, but occasionally use detergents, you must remember that the Host T6 I use offers superior but gentler agitation, which makes this practice a more viable option.
When I used to use detergents, I'd use a general purpose pre-spray such as Ultra Prep, A Woolsafe version such as Pre-Spray Gold, an agressive one like Prochem Enzyme Pre-Spray and possibly Multi-Pro for Pre-Spray and a spotting solution. I'd then have extraction solutions such as Dry Pro, Crystal Green, Liquid Woolsafe and Fabric and Fibre Rinse. Of all of these, on a regular basis I only carry Fabric and Fibre Rinse. As you can see, micro splitting has made life much simpler. I still hold my usual detergents in stock, but only pull them out for problematic commercial work. They don't normally perform better than M/S'ers, but may be quicker.
Safe and happy cleaning:)
