We have owned our Rainbow sweeper for several years now and it has been exceptional in performance! We are very pleased with this product Billy Martin is excellent at answering our questions, keeping us informed of any changes or new products they offer and overall, just awesome to work with. We were able to get our new sweeper the same day of the demonstration. Billy completed all the paperwork and made it a simple process. At first, the cost may seem higher than usual for a traditional sweeper but this is an exceptional sweeper and when you calculate out the years and years that it takes care of your needs, you will actually be saving money!!! Also, there are no bags to buy or maintain. We use ours continuously as an air cleaner in our son's bedroom and his asthma symptoms have improved greatly. WE LOVE RAINBOW !!!
