30 years ago I tried $1.00 to start, it was a huge mistake. I got every pickup truck bed washer and bucket washer around. It didn’t take long to realize that I needed to go to $1.50 to start for 4 minutes. Today I’m at $2.25 for 3:30 minutes. The first time I got a vacuum full of used Kitty litter I raised my price to $1.00 from .75 and lowered to time from 5 minutes to 3 minutes, I made that move probably 15 years ago. I'm in the process now of raising my vacuum prices to $1.25 for 3:30 minutes. My competition on the other end of town is still at .75 for 5 minutes, he’s a poor operator and I very seldom see any one vacuuming there.
