People don't understand how I can clean so fast and know that it is clean. I have a system. You always have to have a system. It also helps to make sure you get everything in the room. First off, you must do one room at a time. I always start with the kitchen. You always work top to bottom, left to right. If you do this every time you clean, you will always clean in half the time. In the kitchen, I always start with the stove, and work my way around the room. The floor is absolutely last.
