The Shark POWERDETECT upright vacuum combines powerful suction with cutting-edge DuoClean Detect Technology for faster, smarter, better cleaning. It features a network of proprietary Intelli-Sense sensors that do the work for you, automatically sensing and reacting to hidden dirt, floor types, edges, corners, and the direction the vacuum is moving. Two-brushroll system with four Intelli-Sense sensors automatically senses and reacts to hidden dirt, debris and hair, and boosts suction and brushroll speed for optimal performance. EDGE DETECT™ automatically increases suction power within two inches of an edge or wall for maximum cleaning performance along edges, corners, and under baseboards, eliminating the need for extra attachments or a broom and dustpan.
