Verdict

The Shark NZ691UKTDB is a mains-powered, bagless corded upright vacuum cleaner in an exclusive black finish, powered by a 750W motor and featuring a 1.1-litre dust capacity. Main characteristics include an 8-metre power cable, an anti-allergen complete seal trapping 99.9% of dust, and dual floor modes with handle controls to easily transition between carpets and hard floors. Prominent pros highlight its signature Anti Hair Wrap technology that actively clears hair from the brush-roll, its Lift-Away feature that converts the unit into a lightweight portable cleaner for stairs, and a specialised pet tool with an air-driven brush roll. On the downside, cons include its heavy overall upright weight of up to 7.76 kg (though lighter in handheld mode) and a maximum noise level of 80 dB, which some users find loud.
