Hoover UH70015 Platinum Collection Cyclonic Upright Vacuum The Hoover Platinum Collection Cyclonic Bagless Vacuum combines WindTunnel Technology and Multi Stage Cyclonic Filtration to remove more dirt from carpet than other bagless and cyclonic uprights. Hoovers Patented WindTunnel Technology features three distinct air tunnels to lift and remove dirt from carpets. WindTunnel Technology prevents dirt from scattering back onto your clean floor, so you can remove dirt in less time. Multi stage cyclonic filtration system means that the air going thru the filter is cleaner than the air that was pulled into the vacuum so that the filter will stay clean longer, and the vacuum will have no loss of suction when cleaning. Filter made with HEPA media. HEPA media traps 99.97 percent of dirt, dust, and pollens down to 0.3 microns, for cleaner air than standard or allergen media. An easy, integrated reminder tells you when to clean your lifetime washable filter, and automatically registers your next cleaning date. Embedded Dirt Finder, EDF, uses real time sonic technology to tell you when dirt is being removed from your carpet. Once the dirt has been removed from your carpet, the Embedded Dirt Finder indicator turns from red to green, indicating that your carpet is clean. This vacuum features a power button located conveniently in the handle, right where it is needed, and a push button floor selector to adjust your vacuum to the ideal height setting for maximum cleaning effectiveness. Other features include a high intensity LED headlight to illuminate your cleaning path, non marring wheels to ensure floors wont get scratched, and an extra long 40 ft cord that gives you the freedom of uninterrupted cleaning.
