I have avoided these for years, and the more people gush the more I gag, HOWEVER. I did the in-home demo with Christy Jackman, and I fell in love! Oh my gosh! I have adored my Riccar for my whole adult life and felt confident it would hold its own against the rainbow……Not even close! Christy’s presentation was zero pressure, show me the results and let me decide for myself. It’s been 2 weeks now and it’s astonishing the difference in my carpet. It looks nearly new, and it’s 14 years old! The rainbow removes even oils from the fibers to the point that I can see the dark spots in contrast that actually will need a shampooer….which I got free as part of the weekly deal! I’m a believer!
