Thats the first thing I learned as a ChemDry franchissee, 13 years ago, DIVERSIFY, from starting offbeing a carpet cleaner, now I am into a few related businesses, fire/flood restoration, leather cleaning, van hire, biodiesel, renting out houses, limo hire and builders cleans, all these things are carpet cleaning related and so long as they fit my criteria for ROI the list will be added to.
