Shark Sonic Duo promises a quick, powerful, and easy way to remove stuck on dirt that holds allergens and odors from carpets, area rugs, and hard floors. It is a total floor care system that cares for, cleans, and finishes all hard floor surfaces and carpets. It is convenient to use and provides a better clean with less effort every time. Carpets and area rugs are rejuvenated and left looking cleaner and brighter, and smelling fresher. To get your carpets truly clean, the Sonic Duo first removes the visible dirt on the surface of the carpet. Then the carpet solution with trap and remove technology penetrates deep and attaches to the stuck on dirt down deeper into the fibers. As the solution dries, it dehydrates the stuck on dirt, unlocking it from the fibers so it is easily vacuumed away later. Hard floors are deep cleaned and are left with a beautiful non streak finish with no dulling residue. To get your hard floors truly clean, the sonic action and specially formulated cleaning solution work together with the pad to get rid of the dirt, even down into the cracks. The Shark Sonic Duo comes with 2 scrub modes that allow you to further tailor your cleaning process to your unique floor care needs. The washable pads and concentrated non-toxic cleaning solutions add value. For replacement chemicals see Model No RU832 Hard Floor Cleaner, RU332 (SKU 601830) Carpet Cleaner, and RU603 Hard Floor Polish. 2 year warranty.
