The Rainbow cleaning system is the highest quality water filtration vacuum cleaner on the world market today. Manufactured in the United States since 1935 Rainbow offers superior quality and performance. The Rainbow combines 'water wash technology' with 'HEPA filter technology' to provide the cleanest and healthiest air possible. Others can make the claim but water filtration is truly the only known system that does not lose suction or airflow as you pick up dirt.
