Shark PowerDetect Corded Upright Vacuum (AZ3900UKT, Teal/Silver)

How does the DuoClean Detect technology work?

DuoClean Detect uses two brush-rolls working together with intelligent sensors that automatically detect your floor type and debris levels. The front brush-roll engages carpets to pull out embedded dirt, whilst the rear brush-roll captures large debris and fine dust from hard floors. The sensors continuously monitor cleaning performance and adjust brush speed and suction power accordingly, eliminating the need for manual mode changes.

What makes the DirectionDetect system different from standard vacuums?

DirectionDetect allows the vacuum to clean effectively in both forward and reverse directions, providing 40% faster debris pickup. Traditional vacuums only clean efficiently when pushed forward, requiring multiple passes. This system adapts to your cleaning direction automatically, meaning you can pull the vacuum backwards whilst maintaining full cleaning performance, significantly reducing cleaning time and effort.

How heavy is the vacuum and is it difficult to manoeuvre?

The vacuum weighs 7.72kg, which some users find substantial during extended cleaning sessions. However, the weight contributes to its powerful motor and robust construction. The vacuum features smooth-rolling wheels and ergonomic handle design to reduce strain. Many users report that despite the weight, it glides well across surfaces and the Powered Lift-Away feature reduces the weight when cleaning stairs or above-floor areas.

What is included with the Powered Lift-Away feature?

Powered Lift-Away transforms your upright vacuum into a portable cleaning system. The motorised pod detaches at the push of a button, maintaining full suction power for cleaning stairs, furniture, car interiors and tight spaces. It includes three attachments: a Motorised Pet Tool for upholstery and pet hair, a Crevice Tool for narrow spaces and a Multi-Surface Tool for general above-floor cleaning.

How effective is the Anti-Allergen Complete Seal system?

The Anti-Allergen Complete Seal captures and traps 99.9% of dust and allergens using HEPA filtration technology. The sealed system includes multiple filtration stages that prevent particles from escaping back into your home's air. This makes it particularly suitable for households with allergy sufferers or asthma, as it effectively removes microscopic particles including dust mites, pollen and pet dander.

Does the Anti Hair Wrap Plus really prevent hair tangles?

Yes, the Anti Hair Wrap Plus technology actively prevents hair and fibres from wrapping around the brush-roll. The self-cleaning brush system automatically removes tangled hair and threads during operation, maintaining consistent cleaning performance. Users with long hair or pets report significantly less maintenance compared to traditional brush-rolls, with the system effectively handling both human hair and pet fur without manual intervention.

What is the capacity and how often do you need to empty it?

The vacuum has a 1.3-litre dust capacity, which typically handles a week's worth of cleaning for average-sized homes. The transparent canister allows you to monitor fill levels easily. Emptying is straightforward with a bottom-release mechanism, though it requires two hands to operate safely. The large capacity means fewer interruptions during cleaning sessions, particularly beneficial for larger homes or deep cleaning tasks.

How long is the power cord and does it reach far enough?

The vacuum features an 8m power cord, providing good reach for most rooms without changing sockets. However, some users in larger homes report wishing for an additional metre of cord length. The cord retracts automatically and the vacuum's efficient cleaning pattern means you can cover more area per socket position. The corded design eliminates battery concerns and provides consistent suction power throughout your cleaning session.
