Verdict

The Shark NZ801UKTBK is a corded upright bagless vacuum cleaner featuring a 750W motor, a 0.83-litre dust capacity, and an 8-metre power cable. Its main characteristics include a DuoClean floorhead with two motorised brush-rolls for seamless transitions between carpets and hard floors, Powered Lift-Away technology to convert the machine into a portable unit, and an Anti-Allergen Complete Seal with HEPA filtration that traps 99.9% of dust and allergens. The main pros of this model are its exceptionally powerful suction, front-facing LED headlights that reveal hidden dirt, and integrated Anti Hair Wrap technology which actively prevents hair from tangling around the brush-roll, making it highly effective for pet owners. However, prominent cons include its relatively heavy overall in-use weight of approximately 7.3 kg and a maximum operating noise level of 80 dB, which some users may find bulky and loud during extended cleaning sessions.
