Shark Technology With Shark's revolutionary Stratos IZ400UK, you can clean your house to a whole new level. This model, which incorporates their exclusive Anti Hair Wrap Plus technology, offers Shark's best-ever hair pick-up thanks to an improved brush roll design. You won't ever have to manually untangle the floorhead again if you remove long, short, and pet hair as you clean. Additionally, this model has Clean Sense IQ technology. This ingenious function intelligently adjusts the power to clear up to 50% more filth by automatically recognising the debris you can't see. The suction power is illuminated by an intelligent indicator in the floorhead, which rises to match the need of the task at hand and falls back when the dirt is removed. Additionally, the vacuum's interior is protected from unpleasant odours with anti-odor technology. To choose an intensity setting, simply rotate the dial while it is inserted into the floorhead. Use Shark to prevent dust cup odours.
