"The cleaning the Rainbow offers is far superior to anything we have ever seen or used before. It puts our other big name vacuum cleaner to shame. It's deep cleaning abilities are unmatched! The Rainbow completely traps dust, dirt, and other allergens it removes from carpets, upholstery, vents, and smooth surfaces in water thus improving our families air quality. The Rainbow is so fun and easy to use. Our teenagers even enjoy cleaning the house with it! When we are not busy vacuuming, our Rainbow is plugged in and hard at work purifying the air in our home. A vacuum that doubles as an air purifier! This purchase was really a no-brainer. Yes, my husband and I have been hooked on our Rainbow ever since our first in-home demonstration. We will never own a different home cleaning/purification system."
