Verdict

The Shark PowerDetect HZ4000UKT is a 370W corded bagless stick vacuum cleaner weighing 4.47kg and featuring a 10-metre power cord alongside a 0.3-litre dust capacity. It is highly characterized by its DuoClean Detect floor-sensing technology, Anti Hair Wrap Plus brush-roll, and DirectionDetect capabilities for picking up debris in both forward and reverse directions. Main pros include its powerful suction that delivers upright-performance cleaning, an Anti-Allergen Complete Seal with HEPA filtration, a flexible Flexology wand for under-furniture reach, and a specialized pet tool for dealing with fur. Notable cons are its stiff and rigid power cable that can be difficult to wind or uncoil, a relatively small 0.3L dust canister that requires frequent emptying, and a top-heavy design that easily falls over unless folded down into its storage position.
