Dyson V15 Detect Review: Is the Laser Worth £300 More Than a Shark?
Five years on, the V15 Detect is still on sale at £649.99 and still tops its testers’ charts for suction. The real question is not whether it is good. It is whether a green laser, a dust counter and a lighter machine are worth what they cost over the Shark Stratos at around £249. At today’s prices the gap is not £200. It is £310 to £400.
Where the reviews line up
We put together three kinds of evidence. There are two timed UK editorial tests, from Expert Reviews and Trusted Reviews, with TechRadar as a third opinion. There is the lab-style test from Vacuum Wars, a US specialist that measures every machine it reviews the same way. And there are buyer ratings at Dyson, Argos and PriceSpy, the largest being 18,079 ratings on Dyson’s own site. On the vacuum itself they agree to an unusual degree.
It is very powerful. Vacuum Wars calls it the most powerful cordless it had tested when it reviewed it, and gives it a perfect 100 on carpet deep cleaning. Expert Reviews calls it “the best cordless vacuum you can buy right now”. The laser works: every tester who used the Fluffy Optic head says it shows up dust you would not otherwise see, though only on hard floors. The particle counter splits opinion. Expert Reviews says “I don’t see the benefit”, while Trusted Reviews and Vacuum Wars like it because it drives the Auto mode, which raises power on dirty patches and saves battery on clean ones.
The 60-minute claim is an Eco-mode, hard-floor figure. Measured on Eco, it ran 50 minutes for Expert Reviews and about 60 for Trusted Reviews and TechRadar. On Auto both of those got about 40 minutes. On Boost they got 10 to 18, and Expert Reviews timed 11. Recharging takes about 4½ hours.
Is it worth the extra over the Shark? For most homes, not at today’s prices. On 6 October 2026 the cheapest new V15 Detect Absolute on PriceSpy was £559, against £249 for the Shark Stratos on 18 September. That is a £310 gap, and £400 at Dyson’s own £649.99. You get a machine about a kilo lighter (roughly 3.1 kg against 4.1 kg), stronger peak suction and the laser. You give up Shark’s five-year guarantee for Dyson’s two years. If you have lots of hard flooring, weight matters to you and you can catch it on offer, the case gets much stronger. At full price it is a luxury, not a necessity.

Before the review: is it still on sale, and which V15?
Yes, but stock is patchy. On 6 October 2026 Dyson’s V15 range page listed the V15 Detect Absolute at £649.99 as in stock, while its individual product page and the gold Absolute+ and Extra versions showed out of stock. Currys (£649), Argos (£650) and Very (£649, via PriceSpy) were all selling it. Dyson’s newer V16 Piston Animal (£749.99 at Euronics, with a 1.3-litre bin and a 70-minute claim) sits above it. The V16 is a different machine and is not reviewed here. Several V15 names are around: Absolute, Absolute+, Extra, Total Clean and Absolute Pet. The motor, battery and bin are the same, but the tools in the box differ, so check the box list before you compare prices.

Expert Reviews and Trusted Reviews
Expert Reviews tested it at £599 and timed 50 minutes on Economy and 11 on Max, with a 4½-hour recharge. It weighed it at 3.08 kg and called that its main practical drawback, tiring on thick carpet. It found the laser “phenomenal at picking out microscopic dirt”. On the acoustic particle counter Shaw is blunt: “I have to admit I don’t see the benefit of this.” If you can see the bin filling, he asks, what does a running count add? His verdict is still that it is the best cordless you can buy, with the price as the barrier.
Trusted Reviews measured more and reached the opposite view on the counter. Its figures are more than 60 minutes on Eco, about 40 on Auto and about 10 on Boost. Measured suction was 280.93 AW on Boost, against Dyson’s 240 AW claim. Noise was 67, 69.8 and 71.7 dB across the three modes. It rated the edge-cleaning “the single best performance I’ve seen”. It treats the sensor as essential because it drives Auto mode, which “gives you quality cleaning with the best possible battery life”. TechRadar (4/5, updated August 2024) sits in between. One of its testers found the laser “a little superfluous”, the other liked it, and both praised the dust display. Its numbers are 59–61 minutes on Eco and 40 on Auto, with 18 minutes on Boost where the other two got 10 to 11, and 81 dB. We cannot explain the Boost difference and have printed all three.

A short demonstration of the laser on the Fluffy Optic head, the feature the testers argue about. It appears to be promotional, so watch it for what the laser shows, not for a verdict.
Watch on YouTube ↗Vacuum Wars
Vacuum Wars is useful because it puts every vacuum through the same sealed-suction, airflow and carpet deep-clean tests, so its V15 numbers can be set against its other results. It found the V15 matched the V11 Outsize for sealed suction and airflow at the head, and edged it on unsealed suction and wand airflow. It called the V15 the most powerful cordless it had tested at the time. On its embedded-dirt carpet test the V15 scored a perfect 100. The page has been kept up to date: the V15 is its 2025 overall runner-up for best cordless.
On the gadgets, Vacuum Wars does not see a gimmick. It says the laser showed dust “we wouldn’t have otherwise been able to” see, even in decent light and especially under furniture. It calls the particle sensor “very important” because it adjusts suction automatically. Its complaints are practical ones. There is no auto-empty dock, and the floorhead’s front gate makes the machine hard to push on carpet at full power. Be careful with its figures: it is a US site, it quotes 68 minutes where Dyson UK says 60, and it gives the bin as both 880 ml and 0.76 L. The test results are its strength, not the spec table.
Watch: Does it Suck?
A V15 Detect review video that showed up under this title in searches for Dyson V15 Detect reviews. It could not be opened from here, so we cannot confirm the channel or the full title.
Watch on YouTube ↗Dyson, Argos and PriceSpy buyers
Dyson’s 18,079 is by far the biggest sample, but read it carefully. It is hosted by the maker, and the same 4.6 from 18,079 appears on the Absolute, Absolute+ and Extra pages. So it is pooled across every V15 version, not counted for one box. The more telling number may be that only 71% would recommend it to a friend, which sits oddly beside a 4.6 average. Argos’ 77 reviews (4.7/5) are on a page that sells it at £650. PriceSpy’s 4.5/5 from 17 is small but not tied to one shop.
None of these is a test. They tell you owners are broadly happy, not why the other 29% are not. For a longer view, the video below is billed as a two-year owner’s review. The things a long-term owner would care about are the swappable £89.90 battery, a filter that has to be washed monthly and then left 24 hours to dry, and a two-year guarantee where Shark gives five. Dyson says it registers the guarantee for you if you buy direct. Euronics says you must register yourself if you buy there.

Here is how it compares with the three vacuums we have already reviewed:
| Vacuum | Price we found | Weight | Run time (measured) | Guarantee |
|---|---|---|---|---|
| Dyson V15 Detect | £559–£650 (6 Oct 2026) | About 3.1 kg | About 40 min Auto; 10–18 min Boost | 2 years |
| Shark Stratos IZ400UK | £249 (18 Sep 2026) | 4.1 kg | 54 min minimum; about 10 min maximum (Which?) | 5 years, registered within 28 days |
| Gtech AirRAM Platinum | £238.99–£349.99 (6 Oct 2026) | 3.3–3.4 kg | 50–54 min (Which?) | 2 years |
| Henry HVR160 | £164.99–£184.99 (5 Oct 2026) | 7.5 kg | Corded, so unlimited | 2 years (3 via MyHenry) |
We have taken the figures for the other three straight from our reviews of them. Against the Shark, the Dyson’s extra £310 to £400 gets you three things: about a kilo less to carry, the laser on hard floors, and peak suction that tops the specialist charts. The Shark’s answers are a five-year guarantee and a price at roughly 40% of the Dyson’s. Against the Gtech, the Dyson has much more power on carpet but runs for less time on Auto. And if you have one floor, no stairs and do not mind a hose, the Henry cleans at well under a third of the price. It just never runs out.
Strengths and weak points
What holds up
- Suction: a perfect 100 on carpet deep clean (Vacuum Wars) and 280.93 AW measured on Boost (Trusted Reviews).
- The laser genuinely shows fine dust on hard floors — every tester who used it agrees.
- Auto mode, driven by the particle sensor, gives about 40 minutes with power where it is needed.
- Swappable click-in battery: a spare doubles your run time, and a worn one is a £89.90 part, not a new vacuum.
- About a kilo lighter than the Shark Stratos.
- Anti-tangle heads praised by Expert Reviews and TechRadar.
What people complain about
- Price: £559 at the cheapest we found, £649.99 from Dyson.
- Boost lasts 10 to 18 minutes, and recharging takes about 4½ hours.
- Still 3.1 kg, and tiring on thick carpet or used handheld (Expert Reviews, TechRadar).
- The laser only works on hard floors, with one head.
- The particle counter is a novelty for some testers.
- Only a two-year guarantee, where Shark offers five, and the spare battery was out of stock at Dyson on 6 October 2026.
- The filter must be washed cold every month and dried for a full day.
Who it actually suits
Buy it if you have a lot of hard flooring, you want the strongest cordless suction you can easily buy, and you care about weight. Above all, buy it if you can get it near the bottom of its price range. The swappable battery is a real long-term advantage: a spare doubles your run time, and an ageing battery becomes an £89.90 part rather than a reason to replace the machine.
Look elsewhere if you would be paying full price for features you will stop noticing after a month. In that case the Shark Stratos at around £249 with five years’ guarantee is the better buy. If you want long run times without Dyson prices, try the Gtech AirRAM Platinum. If you want a tank that never runs out, the Henry HVR160. And if you want Dyson’s newest flagship, that is now the V16 Piston Animal at £749.99, which we have not reviewed.
What we could not check
- The videos. All three were confirmed by appearing in two differently worded search listings, not by opening them, because YouTube does not load from our research setup. None of the listings named the channel. “Does it Suck?” is the title exactly as the search showed it and may be cut short.
- Which V15 Dyson is actually shipping. Dyson’s range page showed the Absolute in stock while its product page showed it out of stock, both on 6 October 2026. Check at checkout.
- A UK refurbished price. The only UK refurbished V15 we found, a Dyson outlet listing on eBay, had expired. We have no current UK figure.
- Running cost. Dyson does not publish the battery’s watt-hours or how much power a charge draws, so we cannot work out a cost per charge at the 26.32p/kWh price cap. It is likely to be pennies, but that is not a figure we can give you.
- Which?’s verdict. We did not see a public Which? score for the V15 Detect and did not pay for one.
- Why TechRadar timed 18 minutes on Boost when Expert Reviews timed 11 and Trusted Reviews about 10. The test conditions are not published.
- Noise. The two decibel figures we have (71.7 dB and 81 dB on Boost) were measured in different ways. Neither is Dyson’s figure, and Dyson does not publish one.
- The Dyson rating’s scope. The 18,079 ratings seem to be pooled across all V15 versions. Dyson does not show a count for each model.
- Battery life over years. No source measured how much run time a V15 battery loses after two or three years.
