Are Dyson products worth buying? Vacuum cleaners, fans and more compared
Over the years, Dyson has created some famously innovative designs for a host of everyday technology, including vacuum cleaners, hair dryers and fans.

Below, our experts take a closer look at Dyson's home appliances and explore how they compare to rivals for features and price.

What is the best Dyson cordless vacuum cleaner?
Most cordless Dyson vacs (the brand dropped its corded range in 2018) feature a lightweight, handstick design, and Dyson's signature colouful and see-through plastic styling.
You typically get turbo and soft-roller floorheads, and can swap between them depending on the surface you're vacuuming.
We've also seen Dyson bring in dirt ejectors, allowing you to empty the dust container without (in theory) getting your hands grubby.
Our expert says:
'Dyson has a deserved reputation for quality on the whole, but it's not always the best for battery life. Some models will barely last 10 minutes of cleaning on maximum power. You could get double that with rival vacs.
'So, while Dyson will be the go-to choice for many, it's worth considering all cordless vacuum options before handing over your cash.'
Andrew Laughlin, Which? vacuum cleaners expert
We've tested a vast selection of cordless Dyson vacs, including the following:
- Dyson V11 Advanced – The LCD display shows you how long the battery will last on each setting, so you can reduce the power if you want the battery to last longer. It will also indicate when you need to clean the washable filter.
- Dyson V12 Detect Slim Absolute – A lightweight bagless vacuum cleaner with three power modes: auto, eco and boost. When you're ready to tackle a dirty floor, you can choose from a motorised cleaner head with de-tangling technology and an illuminated cleaner head with a built-in laser.
- Dyson V15 Detect Absolute – Designed to tackle pet hair, this vacuum cleaner has an LCD display to show how much battery you have left. According to Dyson, it can detect and remove hidden dust in your home for 'scientific proof of a deep clean' – we've tested its effectiveness as part of our full review.
- Dyson Gen5detect – Dyson bills this as its 'most-powerful vacuum cleaner yet', claiming it has the brand’s longest runtime in a cordless vacuum. It has single-button power control and includes a fluffy optic floor head, which uses a green laser diode to illuminate hidden dust.

What is the best Dyson robot vacuum cleaner?
Dyson launched its first robot vacuum cleaner, the Dyson 360 Eye, in 2016. A couple of years later, the brand rolled out the Dyson 360 Heurist.
The latest model is the Dyson 360 Vis Nav, which is described as its 'most powerful robot vacuum' yet, and features a triple-action brush bar to deep clean across all floor types.
Typically costing over £1,000, the robo-cleaner doesn’t come cheap. To see if the 360 Vis Nav is worth your money, we’ve put it through our cleaning and navigation tests — including measuring dust pickup, how well it tackles pet hair and how effectively it handles obstacles around the home.
Generally speaking, our tests have shown that, while convenient, robot vacs can't yet match their full-sized competitors for cleaning power. Ultimately, you'll still have to whizz round with a regular or handheld vacuum if you want to keep your home spotless.
You can check in with our Dyson 360 Vis Nav review, or shop from the following stores:

Which Dyson air purifier is best?
The best air purifiers effortlessly capture dust, pollen and smoke in your home. If you suffer from dry skin or sinus congestion when the air is dry, a humidifier could help.
Interestingly, Dyson models are built to heat or cool your room while they clean. However, you'll pay a premium – the cheapest on-test model at the time of writing costs around £550. Our testing has uncovered Which? Best Buys from rival brands that are far cheaper.
Our expert says:
‘You'll likely pay a premium for a Dyson air purifier, but that hefty price gets you smart features, night mode, a timer, as many as 10 fan speeds, and an air quality sensor for automatic air purification.
'They’re typically multipurpose appliances, too, with some doubling up as a heater in winter and/or a fan in summer. So you’re often getting two or three appliances in one if you opt for a Dyson air purifier.
‘One claim Dyson makes for several of its models is that they destroy formaldehyde, which is a gas given off by some household furnishings, furniture and cleaning products. We’ve recently made our expert lab tests even more exacting, and now test to see if Dyson’s claims hold up.'
Patrick Gallagher, Which? air purifiers expert
We've tested the following Dyson air purifiers:
- Dyson Big+Quiet Formaldehyde BP03 – The BP03 has HEPA and carbon filters, plus 10 fan speeds to choose from. You can control the air purifier remotely via the MyDyson smartphone app.
- Dyson Purifier Cool Formaldehyde TP09 – This air purifier may be pricey, but it is multipurpose, doubling as a fan. For air purification, it has a HEPA filter to trap particles, a carbon filter to remove gases, and a catalytic oxidation filter to eliminate formaldehyde.

Which Dyson fan is the best?
Dyson’s tower fans are famously bladeless and, like many other products in the brand's line-up, they don’t come cheap. A Dyson electric fan could potentially be a highly stylish addition to your home – but it's only worth picking up if it scores well in our review.
For each electric fan in our lab, we test the full range of air speeds. Our experts look at how well the fan ventilates a room with cool air from outside (if you place it near an open window), plus we measure power use at each fan's lowest and highest speeds.
If you're keen to stick with Dyson, expect to spend around £350 on the Dyson AM07 – but note some of our Best Buys are a fraction of that price.
Our expert says:
'Dyson fans feature a bladeless design and many people are drawn to them on looks alone. However, several features are similar to other fans, including oscillation mode, a programmable timer and remote control.
'Our tests include a wind speed assessment with an anemometer, as well as a noise level check to ensure we recommend quiet fans that won't drive you crazy with incessant whirring. We also run a blindfolded panel assessment to determine how pleasant and consistent the breeze feels.
'There's no doubt Dyson fans look super-stylish, but only our rigorous tests reveal whether their performance matches up.'
Sam Morris, Which? electric fans expert
At the time of writing, we've published reviews for the following Dyson fans:
- Dyson AM07 – This tower fan is just over one metre tall but only 23cm wide, so it won’t take up too much valuable floor space. The brand's Air Multiplier technology creates a breeze and changes speeds without the need for spinning blades.
- Dyson AM09 Hot & Cool Fan Heater – This bladeless fan from Dyson has 10 settings and can also be used as a heater.
Discover which fans have soared through our tests with our guide to the best electric fans.
Should you buy the Dyson Supersonic or Airwrap hair dryer?
The Dyson Supersonic and Airwrap are two high-end hair tools with different purposes. When we test hair dryers, we look for brilliant drying and styling results.
Dyson Supersonic
Let's start with the Supersonic, which is branded as a professional hair dryer and claims to offer fast drying with low heat. It partners with a range of attachments for different styling needs and usually costs around £300. You can learn more with our Dyson Supersonic review.

Meanwhile, the Dyson Airwrap is branded as an all-round hairstyling tool. It claims to work as a dryer, curler, straightener and waver, all without relying on excessive heat. Think of it as an all-in-one hairstyling toolkit, more for those seeking the whole package.
According to search data, the Airwrap is one of the most popular styling tools around, but it comes at a high price and usually costs more than £450.
The Dyson Airwrap is available from the following stores:
Note Dyson also has some cordless straighteners in its range, too – we've reviewed the Dyson Corrale.

Is it worth buying Dyson’s headphones?
The Dyson Zone Absolute+ headphones are one of the brand’s more unusual releases. These wireless, over-ear headphones come with an intriguing feature: an air-purifying visor that attaches to the headphones magnetically. Each earcup also contains a motor, air-purifying filter and compressor fan.
Dyson's attention-grabbing headphones typically cost more than £500, which is a significant investment. Our rigorous tests have uncovered plenty of more affordable Best Buy options.
We first set eyes (and ears) on the Dyson Zone Absolute+ headphones in our first look review back in 2023.
