I Have 15 years of experience, starting in the Seattle area and I have recently moved here to Arizona.
Great question, it depends on the kind of carpet or fabric on furniture. the more the pile or thickness, it will take a little more time to dry. You can walk on carpet while drying just make sure to wear just socks, no shoes. Tile we ask you not to walk on it till dry. When it comes to tile it dry's in a short time.
I have a flexible schedule which does contain some weekends. I will work days or nights. I try to make it easy for the customers schedule.
