Shark PowerDetect Speed review: The cordless vacuum to beat in 2026

In 2024, Shark released what quickly became our favourite cordless vacuum cleaner of the year – the Shark PowerDetect Pet. At the time, it felt like it was operating in a completely different category when it came to performance, innovative features and Shark’s clever DirectionDetect cleaning technology.

Since then, plenty of other brands have jumped onto similar ideas, meaning the PowerDetect doesn’t feel quite as groundbreaking anymore, but there’s no denying it was a real game changer when it first arrived.

Now, Shark is back with an upgraded version in the form of the Shark PowerDetect Speed, so naturally, we were excited to put its new features to the test. It wasn't long before I realised the brand has successfully done it again, delivering another range of smart innovations that could just knock the original to the side.

Price and availability

The Shark PowerDetect Speed comes in three different variants. The flagship model includes the Auto-Empty Base and costs £500/$500, which is the version I've been testing.

If you’d prefer something a little cheaper, there’s also a version without the Auto-Empty Base for £400/$430, alongside a Pet Edition that includes Shark’s FurFins Pet Tool for tackling stubborn pet hair. That model costs £430, although it’s currently only available in the UK.

At the time of writing, the PowerDetect Speed without the Auto-Empty Base is heavily discounted on Shark’s website by a rather generous £170, so it’s definitely worth checking out if you don’t mind emptying the dustbin more frequently.

Unboxing and set up

As with most Shark cordless vacuums, the PowerDetect Speed arrives in a surprisingly compact and lightweight box. Everything inside is packaged using recyclable materials and paper wrapping for the smaller accessories, which helps keep things relatively eco-friendly.

Inside the box, you’ll find the main vacuum body, the primary floorhead, the Flexology wand, charging post and dock base. Setup was incredibly straightforward – all I had to do was click the charging post into the dock and attach the vacuum components together. The whole process only took a few minutes and felt very self-explanatory, although there’s also a quick-start guide printed directly onto the box if you need it.

The only other setup step involved inserting the anti-odour cartridge into the dock, which was just as simple as it sounds. After that, I popped the PowerDetect Speed onto the Auto-Empty dock to charge and started digging into the specs.

Design and features

It’s immediately clear that Shark has designed the PowerDetect Speed to feel slimmer and lighter than some of its previous cordless models, whilst still retaining the powerful cleaning technology the PowerDetect range is known for. It weighs around 3.5kg, and the new Ultramarine finish feels more stylish than earlier models.

Like many recent Shark vacuums, the PowerDetect Speed uses the brand’s Flexology wand design, allowing the vacuum tube to bend so you can clean underneath sofas and low furniture without crouching down. The floorhead itself also fairly low-profile, helping it glide into tighter spaces more easily.

Depending on the model you choose, Shark’s Auto-Empty system can automatically empty dust and debris into a larger sealed container after each clean. Shark says it can hold up to 45 days’ worth of dirt before needing emptying, whilst also charging the vacuum and storing spare attachments neatly in one place. The onboard dustbin only offers a 0.5-litre capacity, but the larger 2-litre dock capacity more than makes up for this.

One of the standout features remains Shark’s PowerDetect Intelligence system. This combines four separate detection technologies – Floor Detect, Edge Detect, Dirt Detect and Direction Detect – which automatically adjust suction and brushroll performance depending on what the vacuum senses in front of it.

This was one of the most exciting things about the original PowerDetect in my opinion, so I’m really glad Shark has kept it here. This also allows the vacuum to detect dirt levels, floor types, edges and corners, boosting power exactly where it’s needed without you having to manually switch settings yourself.

Shark has also included its TurboDrive Detect floorhead and Self-Cleaning Brushroll technology, both of which help improve pickup across carpets and hard floors whilst preventing hair wrap from building around the brush.

The vacuum also introduces Shark’s new 'Reveal' technology, which uses a precision-angled cyan beam to highlight hidden dust on hard floors. It’s more of a blue light compared to Shark’s usual white headlights, but it does a great job of revealing tiny particles you’d otherwise never notice. Cleverly, the light automatically changes back to white when the vacuum detects carpet through its Floor Detect technology.

Battery life comes in at around 60 minutes on a full charge in Eco mode, which isn’t the best we've seen but is still perfectly respectable for a cordless vacuum. The six-hour charging time is a little longer than I’d ideally like, but again, it’s fairly standard for this category.

The LCD display is another nice addition, showing the Dirt Detect system working in real time, changing colour depending on how much debris the vacuum detects and how much suction power it’s applying. The screen also displays charging information, although I would’ve loved to see the battery shown as a percentage rather than a simple icon. That’s admittedly a fairly minor complaint, but it’s something I’ve appreciated on rival models.

Performance

Overall, I’ve been really impressed with the PowerDetect Speed and far from disappointed with the successor to my current favourite cordless vacuum. Cleaning performance is exceptional, and the suction power is still amongst the best I’ve tested.

A lot of this comes down to Shark’s detection technology, but it really does make a noticeable difference in day-to-day cleaning. You never have to think about changing settings between different floor types because the vacuum handles it all automatically. There’s something reassuring about knowing it’s already adjusted itself correctly for the surface underneath, which not only improves cleaning performance but should also help protect the vacuum long term.

My home is primarily hard flooring, but the PowerDetect Speed also handled carpets and rugs extremely well. It moved smoothly across a wide range of surfaces without feeling too heavy or awkward to manoeuvre.

The Flexology wand is another huge plus, allowing you to bend the vacuum underneath furniture without having to drag things out of the way first. Combined with the lightweight design, it makes the whole vacuum feel very easy to use, and would make a good choice for anyone who struggles with mobility.

The attachment selection is well judged too, feeling useful without being excessive. The 20cm Duster-Crevice Tool and Motorised Hand Tool were both brilliant for tackling smaller corners, upholstery and awkward spaces, and I found myself reaching for them regularly. I also really like that they store neatly on the dock itself, keeping everything tidy and cohesive.

One of the biggest benefits of Shark’s Auto-Empty dock is how little maintenance is actually required. You only need to empty the dust container when it’s full, and the dock conveniently displays a warning light when it’s time to do so.

Emptying it works much like any other cordless vacuum, although I’d definitely recommend placing the bin as far inside your household bin as possible, as the dust can come out in quite a dramatic cloud. Still, considering you may only need to do this every 45 days or so, it’s hardly a major issue.

I actually found myself emptying it more frequently simply out of habit, but it was never anywhere close to full, so I can absolutely believe Shark’s claims that it could comfortably last closer to two months in many homes.

It’s also worth mentioning that the Auto-Empty function itself isn’t exactly quiet. The dock goes through a three-step emptying cycle after each clean, which takes roughly 30 seconds in total. Shark has tried to soften this slightly with a 'Quiet Mode', which does help a little, but it’s still something you’ll definitely hear.

Verdict

The Shark PowerDetect Speed successfully builds on everything that made the original PowerDetect Pet such a great cordless vacuum, whilst refining the design into something noticeably lighter and easier to use. Its intelligent detection technology remains unmatched, automatically adapting suction and cleaning performance across different floor types with impressive accuracy. Combined with excellent suction power, thoughtful design features and Reveal lighting, plus the convenience of the Auto-Empty dock, this is easily one of the best polished cordless vacuums Shark has released to date. The dock can be noisy and the battery display could be more detailed, but overall, the PowerDetect Speed delivers flagship-level cleaning performance with very few compromises.

Alternatives to consider

I still absolutely recommend the original Shark PowerDetect Pet, especially since it remains one of the best cordless vacuums around thanks to its excellent performance and smart features. However, the Shark PowerDetect Speed keeps everything that made the original so impressive whilst packaging it into a noticeably lighter design. If that sounds beneficial for your home, then it’s definitely worth the upgrade.

Another strong alternative is the Dyson V16 Piston Animal, which offers very similar smart cleaning features, although without the convenience of an Auto-Empty dock. Even so, for me, Shark still comes out on top day to day, and the PowerDetect Speed remains my personal pick.
