Dyson V15 Detect Review (2026): Is the Laser Worth $739?
The laser head is not a gimmick — but whether it justifies the price depends entirely on your floors.
In this guide · 5 sections
The V15 Detect's headline feature is a green laser angled across the floor ahead of the cleaner head. It sounds like a marketing department's idea. It is, in practice, the most useful thing Dyson has added to a vacuum in a decade — and also the reason this review comes with a caveat about who should buy it.
The laser is the point
Switch the Fluffy Optic head on in a dim room and the floor you thought was clean visibly is not. The effect is psychological as much as practical: you clean until the floor is dark rather than until you are bored. On hard floors this changes the outcome. On carpet, where the laser cannot illuminate below the pile, it does nothing at all.
Suction and the particle counter
The piezo sensor counts and sizes particles hitting the bin inlet, displays them on the screen, and raises suction automatically in Auto mode. It is the rare smart feature that earns its place — full power where it is needed, better battery life where it is not.
Runtime in practice
Dyson quotes 60 minutes, achievable in Eco with the non-powered head. Realistically expect around 40 minutes in Auto with the main floor head, and closer to eight in Boost. For a two-bedroom flat that is comfortable; for a house with stairs and pets, buy the spare battery.

The cheaper alternative
The Shark Stratos does perhaps 95% of the cleaning for $229 less. On carpet, where the V15's headline features do not apply, it is simply the better buy.
Who should buy it
Buy the V15 Detect if your home is mostly hard floors, you have allergies, or you have pets and hair is a daily problem. If your home is mostly carpet, the laser is dead weight and the Shark does close to the same job for considerably less.
Prices were correct at the time of writing and are re-checked automatically, but retailers change them often — confirm on the retailer's page before buying.
Is the V15 Detect better than the V12?
It has more suction and a bigger bin, but the V12 Detect Slim has the same laser head and is lighter. If weight matters more than raw power, the V12 is the better buy.
Does the battery degrade?
Like any lithium battery, yes — expect noticeable decline after three to four years. Unlike older models this battery is user-replaceable.
Is it worth it over a Shark?
On hard floors, yes. On carpet, no — the features you are paying for do not apply.
