SHARK AZ4000 POWERDETECT Upright Vacuum

The SHARK AZ4000 POWERDETECT is a full-size upright vacuum with Intelli-Sense sensors that automatically detect and adapt to different surfaces, dirt levels, edges, and cleaning directions. It delivers Shark's most powerful suction paired with advanced cleaning technology. The DuoClean Detect system combines two brushrolls with smart sensors to handle both carpets and hard floors in a single pass, automatically boosting power when hidden debris is detected. Edge Detect increases suction within 2 inches of walls and baseboards. Floor Detect recognizes surface type and adjusts brushroll speed accordingly. Direction Detect sends suction forward or back depending on which way you push. The self-cleaning brushroll prevents hair wrap, and Anti-Allergen Complete Seal with HEPA filtration traps 99.99% of dust and allergens. At 17.6 lb, it's heavier than stick vacuums but runs on corded power without battery limitations. It works well for whole-home deep cleaning across mixed flooring, especially in homes with pets, high-traffic areas, or allergy concerns. The trade-off is managing the weight and cord, but you get uncompromising suction and intelligent features that handle the thinking during extended cleaning sessions.
