We use Johnson Diversey products right now for your floor care because we feel they have the most reliable and diverse group of floor care products at this time.  We say at this time because this technology changes almost daily and there is always a new product to try.  That is what our R&D does almost on a daily basis.  The challenges that face us become new, all the time in this field and that is why we would never tie ourselves down to just one product line for every situation.
