Dyson V15 Detect Review

The Dyson V15 Detect is best understood as Dyson's statement cordless vacuum: laser-illuminated floorhead, real-time particle counter and HEPA-sealed exhaust in a premium stick. It is the model Dyson positions at the top of its cordless line, and the features genuinely follow from category-leading engineering.

Our assessment is research-based. We analyse manufacturer documentation, official specifications and how owners describe their long-term experience, then apply our buying criteria. We have not physically lab-tested this unit, and we never pretend otherwise.

The V15 is for households that want the best-feeling vacuum experience and can afford a premium cordless stick. It's a strong fit for mixed-floor homes (hard + carpet), allergy-aware buyers who value HEPA exhaust, and pet owners who struggle with invisible dust on hard floors. If you simply need a reliable, cheaper cordless, look at the Dyson V8 Origin+ below instead.

• Laser dust illumination floors you didn't know were dirty
• Live particle count on the LCD (piezo sensor)
• Auto mode adjusts suction to detected dust levels
• HEPA exhaust filter removes allergens from the airstream
• Two batteries included for up to 60 minutes runtime
• Hair screw tool for pet and human hair on upholstery

Laser illumination is the headline feature and it works as advertised — it makes tiny particles of dust visible on hard floors that every other vacuum we've assessed would leave unnoticed. For genuinely clean floors this changes the cleaning ritual.

Filtration is best-in-class for a cordless. The HEPA exhaust captures microscopic particles so the vacuumed air is clean, a real benefit for allergy households.

Runtime and convenience are excellent — two batteries mean you can keep cleaning past the first cell's limit, and the LCD teaches you about your floors' dust load in a way that helps you vacuum smarter.

Premium pricing. The V15 sits at the top of the market and the price reflects it; buyers who don't need the particle counter will pay for a feature they won't use.

Battery runtime still pales next to a corded canister or upright for large homes — a single charge is a planning exercise on big floor areas.

Heavier than cheaper cordless sticks because the flagship motor, battery and tools all live in the wand.

Flick the trigger, guide the head — Dyson's cordless ergonomics are proven. The moment you switch to handheld, the motor stays in the handle so above-floor cleaning feels balanced.

The practical differentiator is the laser floorhead on hard floors plus the hair screw tool for upholstery. On carpet it performs like a top cordless; hard-floor dust visibility is the reason most owners upgrade.

Hard floors (laser mode), carpet, upholstery, stairs and car interiors. Use the soft roller for hard floors and the anti-tangle tool for pet hair.

Empty the bin when it's full, wash the filters monthly per the manual, and clean the laser window with the included tool periodically. Dyson's cyclones keep filters working far longer than bagless rivals from a decade ago.

Value is defensible only if you will use the hard-floor laser and particle counter. For everyone else, strong performance at lower prices makes the V8 Origin+ the more rational buy.

One of the most complete cordless vacuums you can buy, best appreciated by hard-floor households who value genuinely visible clean. It's expensive, but it's the reference point for premium cordless.
