Verdict

The Shark IW3612EUT Detect Clean & Empty is a 240W cordless 2-in-1 stick vacuum cleaner featuring a 21.6V lithium battery that delivers up to a 60-minute runtime in ECO mode. Key characteristics include four automated sensory technologies (DirtDetect, EdgeDetect, FloorDetect, and LightDetect) alongside a QuadClean multi-surface brush roll with Anti Hair Wrap technology. Main pros include a convenient, bagless 2L auto-empty base station holding debris for up to 45 days, an ultra-lightweight 3.3 kg body, an intuitive LED display, and an Anti-Allergen Complete Seal. However, notable cons include a small 0.42L integrated dustbin capacity that requires frequent automated emptying cycles, an 82 dB noise level, and a lengthy 5-hour full battery charging process.
