Most of my custys have some type of "Bissel" unit for kids and pet spots in their homes. I love it when they try to clean a whole room with those units. I was cleaning a rental last week, and a renter came over from a house across the street, asked how much to cloean 2 small empty rooms. I gave him the "minimum" price response, but after seeing the easiness of the job, I cut it by half. He ended up giving me just about what I wanted, cause he was so impressed.
He told me he had spent 2 hours on a 4x4 square by the door with a Bissel, and couldn't move the dirt like my TM. I like the Bissels!
