The BHFEV362D is a cordless vacuum cleaner which is powered by the same lithium ion battery used in the Black & Decker 36v range of garden power tools, meaning it shares battery compatibility with tools such as lawnmowers, grass trimmers, hedge trimmer and leaf blowers. With up to 75 minutes runtime on a single charge, this PowerSeries Extreme stick vac is designed to help get jobs done quickly, easily and efficiently. This 4-in-1 stick vac has a powered anti-tangle beater bar that gives you a deep and powerful clean with less hair wrap and more pick up on surfaces like carpets, leaving your home spotless once you have finished.Three speed settings allow you to vary your speed to suit the job at hand - use the high speed setting for a maximum deep clean on denser materials like carpet, or switch to a lower speed to conserve battery during lighter duty vacuuming.
