I can identify with many others on this thread, starting out in 1985 charging $44.95 for 2 rooms and a hall! Over the years we steadily raised our prices, but the biggest gain we had was running 2 wands on just about every job to cut our time down. That was and still is, our biggest boost for being done with each and every job in a timely manner while still being thorough. I know many have said dual wands do not work very well in residential, but I differ. We never lack for vacuum, and certainly not lacking in the heat department.
what does that extra person REALLY cost you?
