Your Rainbow is the cutting edge of technological advancement in total home cleaning. Your Rainbow allows you to create an environment in your home that is both dust-free and stress-free. Water is the filter, and for the first time in your life, you are now able to create clean fresh-air inside your home. Every time you use your Rainbow to clean, you are capturing the air that you and your family breathes and forcing it through a Certified Air Cleaner. What comes out of your Rainbow and into your home is pure, fresh, water-washed, Certified Clean-Air. In fact, the second you turn your Rainbow on, the air inside your home becomes cleaner.
