The Earth uses water to cleanse itself of surface dirt, airborne particulates, allergen, dust and man‐made contaminants. It washes the air and cleanses the environment in which we live and breathe. It’s only natural. This works great for outside, but what about inside your home? The Rainbow Cleaning System cleans your home the most natural way possible, using The Power of Water®. It not only cleans your home… it creates a healthier living space. So, how does it work? Moving air lifts dust, dirt and debris and whisks it into the Rainbow’s water basin. Dirt and dust are trapped in a swirling water bath. Fresh, water-washed air is returned to your home.
