I use the microfiber system in my medical/hospital settings on a daily basis. Its great system to use if you have a lot of microfiber heads. They need to be changed after each use as youll only spread and move dirt around once they are soiled. Benefits to using, them for me, is the floors dont get soaked (which is important if youre working around an active environment). However, the heavy mop is still there for, well, heavy mopping. Ultimately, I still use both systems. As far as cost, I havent analyzed that yet, but Ill guess that being able to launder them (both mop heads and microfiber heads) youll be able to save on both ends.
