I use my 360I on probably 50% of my jobs. I use it on almost all of my apartments. The othr guys in our valley only use their wands and no prescrub. We have only lost 2 commercial apmt complexs since we started 5 years ago. I give much of my succes to the quality results of the 360 compared to a wand. Simply put, I'm able to save more carpets that the other guys won't. Others are capable, just to lazy and cheap.
