When I was selling Chocolate Brown D2 Chrome Dome Rainbows, we always mopped the kitchen with the machine. It's so easy. Use a half gallon empty milk jug. Fill with warm water and add one tablespoon of your floor cleaner. Vacuum the floor with the Rainbow normally, empty the machine, and leave it empty. Pour about one cup of the solution onto the floor, and with the Rainbow off, scrub with the bare floor brush. This cup of solution should do an area about a yard long by a yard wide. Turn ON the Rainbow and pull the bare floor brush tool slowly backwards, applying downward pressure. It will squeegee up all the liquid. Turn off the Rainbow, and begin the next area. Once you've used all the solution, it's time to empty the Rainbow.
