Verdict

The Shark IW1511UK Detect Pro is a 240-watt, 2-in-1 cordless stick and handheld vacuum cleaner that weighs a highly maneuverable 2.76 kg and features a 21.6V removable lithium-ion battery providing up to 60 minutes of runtime. Its core characteristics include an LED display, an Anti-Allergen Complete Seal HEPA filter, and a QuadClean floorhead with Anti Hair Wrap technology. The primary pros are its ultra-lightweight design and four intelligent deep-cleaning sensors (DirtDetect, EdgeDetect, FloorDetect, and LightDetect) that automatically optimize suction power and brush roll speeds based on debris levels, floor type, wall proximity, and room lighting. However, notable cons include a relatively small 0.42-litre dustbin capacity that requires frequent emptying, a long battery recharge time of 4.5 hours, and mixed user feedback regarding a plasticky, flimsy build quality.
