O grew up with my parents owning the Rainbow vacuum system, and now that I bought my first home I wanted to have something that works just like that... I bought the Kalorik Pure Air Water Filtration Bagless Canister Vacuum, and I am loving it! I get the same results and it only costs a fraction of what I would have had to pay for a Rainbow. I recommend this product to anyone who has hard floor surfaces.... you will not be disappointed!
