The full-sized corded cleaner adapts its suction to dirt, flooring, edges and direction while Powered Lift-Away helps it reach stairs, furniture and car interiors
A Shark upright vacuum designed to collect dirt while moving both forwards and backwards has fallen by £130, with a bundle of pet and detail-cleaning tools included.
The Shark PowerDetect Corded Upright Vacuum Cleaner is currently £299.99 in an Amazon limited-time deal, down from its £429.99 recommended retail price. The 30% discount applies to the black model AZ3900UKTBK.
Its most unusual feature is DirectionDetect, which adjusts the airflow depending on which way the floorhead is moving. Most people naturally pull a vacuum back over the same patch they have just cleaned, and the Shark PowerDetect is designed to continue collecting debris during that return movement rather than relying mainly on the forward push.
That could make it useful in busy homes where floors need regular attention, particularly when pets, children or outdoor shoes keep bringing fresh debris into the room.
The DuoClean floorhead contains two brush rolls and works with several sensors. DirtDetect can increase cleaning power when it senses embedded dirt, while FloorDetect adjusts suction and brush-roll speed according to the type of flooring beneath it.
EdgeDetect is intended to boost suction beside walls and skirting boards, areas that can otherwise require a separate pass with a narrow tool. Together, these functions allow the corded Shark vacuum to adapt automatically as it moves between different surfaces and levels of dirt.
Pet owners may also be interested in Anti Hair Wrap Plus. Its floorhead uses specially engineered bristles and a chevron-shaped design to pull hair towards anti-wrap combs, helping remove it from the brush roll while the machine is running.
No anti-tangle system can guarantee that owners will never need to check the roller, particularly in homes with long hair or several pets, but the technology is intended to reduce the amount that must be cut away manually.
The Shark PowerDetect pet vacuum can also be converted into a portable cleaner using Powered Lift-Away. The main pod detaches from the upright frame while the motorised floorhead continues operating, allowing it to reach beneath furniture without the whole machine needing to lie flat.
The detached pod can also be carried for cleaning stairs, sofas and car interiors. Amazon’s bundle includes pet, multi-surface, anti-allergen and two-in-one dusting and crevice tools, along with a storage bag for keeping the attachments together.
Anti-Allergen Complete Seal technology is designed to capture and contain 99.9% of dust and allergens measuring between 0.3 and 10 microns, based on the manufacturer’s stated test method. A HEPA filter is also fitted, while Anti-Odour technology aims to guard against unpleasant smells developing inside the vacuum.
The eight-metre power cable should allow users to cover a reasonable area before changing sockets. Because it is corded, the PowerDetect upright cleaner does not have a battery that needs charging or a limited runtime, although the cable will not suit everyone after years of using cordless models.
This is also a substantial upright machine rather than a lightweight stick vacuum. Shark lists the exact model at around 7.6kg, so anyone who frequently carries a cleaner between several floors should consider whether that weight will be manageable.
Amazon has awarded the listing its Amazon’s Choice badge and says more than 400 have been bought in the past month. The cleaner has a score of 4.3 out of five from 239 customer ratings at the time of writing.
There is one specification worth checking carefully. Amazon’s product title refers to a 1.3-litre capacity and 750W power, while Shark’s own page for model AZ3900UKTBK lists a 0.66-litre dust cup and 600W rating. Buyers for whom capacity is important should confirm the exact specification with the seller before ordering.
The manufacturer offers a five-year guarantee when the qualifying product is registered and its conditions are followed. Amazon is also advertising free returns, although the price, seller, stock and delivery terms can change during a limited-time promotion.
Readers can view the £299.99 Shark PowerDetect deal and included tool bundle on Amazon while the £130 reduction remains available.
It is likely to suit homes that value strong corded cleaning, pet-focused tools and automatic floor detection, but its full-sized upright design will be less convenient for buyers prioritising a light machine and cable-free movement.
