Dyson’s Biggest Innovations Ranked: From Genuinely Brilliant to Worse Than Before
Dyson is one of the most respected appliance brands in the world, with innovation baked into its DNA. In my role as a TechRadar Homes Editor, I’ve tested almost every Dyson gadget you can think of — from vacuums to haircare — alongside plenty of rival products for context.
I’m often impressed by Dyson’s creativity and engineering ambition. But not every bold idea turns out to be a winner.
Below, I’ve ranked Dyson’s most significant innovations, from best to worst. To keep things focused, I’ve concentrated on vacuum cleaners and haircare tools, although Dyson also plays a major role in the air purifier and fan markets. Some of these ideas genuinely changed how we clean or style our hair. Others, frankly, feel like upgrades on paper but downgrades in real life.
#1. Miniaturized motors
Almost any handheld gadget benefits from being lighter and more compact, and Dyson has pushed this idea further than anyone else.
Take the Supersonic r hair dryer: Dyson shrank the motor dramatically and housed it in a strikingly compact shell. It looks unusual, but it’s a joy to use. The pipe-like design allows for precise airflow, and despite its size, it delivers an impressive blast of power.
Even more mind-bending is the Dyson PencilVac. This cordless stick vacuum hides its entire internal system — motor, filters, battery, and even the dust cup — inside a handle just 1.5 inches (under 4cm) wide. It genuinely resembles a broom handle, yet it works like a full-powered vacuum.
I’ve been testing it at home, and the result is an ultra-light, incredibly nimble cleaner that feels almost impossible from an engineering standpoint.
#2. Laser dust detection
If you want to be horrified by how dirty your floors really are, Dyson has you covered.
Dyson was the first brand to introduce dirt-illuminating laser headlamps on vacuum floorheads. Positioned at exactly the right angle, these ultra-bright lasers cast long shadows that reveal even the finest dust and hair on hard floors.
They’re genuinely useful, making it far easier to ensure every last speck is picked up. They’re also deeply satisfying, and excellent at highlighting areas you’ve been neglecting.
First seen on the Dyson V15 Detect, these lasers now appear on most of Dyson’s newer vacuums, including the Gen5detect and V16 Piston Animal. Plenty of competitors now offer copycat versions, but after testing many of them, very few come close to matching Dyson’s effectiveness.
#3. Automated curling
Dyson deserves credit for revolutionizing hair curling with the original Airwrap. While air-powered, auto-wrapping curlers are now everywhere, Dyson has managed to raise the bar again.
The latest models — Airwrap i.d. and Airwrap Co-anda 2x — introduce a spring-loaded switch that automates the entire curl sequence. Flick it up, and the device handles wrapping, curling, and the cool-shot phase for you.
The timing is customized to your hair type via a quiz in the companion app. Normally, I’m skeptical of apps for simple appliances — but in this case, Dyson gets a pass.
Is it essential? No. I could replicate the results manually with enough attention and timing. But this automation makes styling almost effortless, and because I’m prone to getting distracted mid-curl, the results are consistently better and longer-lasting when the machine does the timing for me.
#4. Ultra-precise particle tracking
Dyson’s flagship vacuums (starting with the V15) can detect the size and number of particles being vacuumed in real time, displaying the data via a colorful bar graph on a screen above the handle. The vacuum then automatically adjusts suction power to clean more efficiently.
I genuinely like this feature — especially the automatic suction adjustment. Watching the bars shift as you clean can also encourage a more thorough job, particularly in dirt-heavy areas.
That said, this innovation lands lower on my list because not all of it feels necessary. Breaking dust down by particle size offers limited practical benefit, and the real-time graphs often feel more like a showcase for Dyson’s engineering prowess than something users actually need. Useful, yes — but slightly over-engineered.
#5. Submarine mopping heads
Dyson’s approach to wet cleaning remains hit-and-miss.
Submarine floorheads allow certain Dyson vacuums to double as wet cleaners, but I haven’t been fully convinced by any of the brand’s mopping solutions so far. The V15s Detect Submarine suffered from a poorly designed head that leaked dirty water when detached, and while the Dyson WashG1 cleans well, its sky-high price is hard to justify.
There are similarly priced — and even cheaper — wet-and-dry vacuums that perform better and offer more features. I do have a Clean+Wash Hygiene unit on the way for testing, so Dyson may yet redeem itself here.
#6. Conical floorheads (a genuine downgrade)
At the bottom of the list is an innovation I actively dislike.
With the V16 Piston Animal, Dyson replaced its traditional parallel brushroll with a dual cone-shaped roller design. The idea is that long hairs travel toward the narrow end of the cones and into the bin, reducing tangles.
In practice, this creates several new problems. The pointed front of the floorhead prevents it from sitting flush against walls, making edge cleaning awkward and frustrating. There’s also a barrier in the center where the rollers connect, beneath which nothing gets picked up.
While the anti-hair-tangle concept does work, I rarely had issues with hair wrap on Dyson’s older floorheads anyway. Unless your household produces Rapunzel-level hair shedding, the downsides here far outweigh the benefits.
