Dyson V15 Detect Vacuum Review: The Last Vacuum You'll Ever Buy

We ran the Dyson V15 Detect across hardwood, carpet, and tile for three months. Here's whether this £649 cordless vacuum justifies the price.

Overview

The Dyson V15 Detect is the first vacuum to use a laser to reveal dust particles invisible to the naked eye — and then count and categorise them in real time on an LCD screen. It sounds like a gimmick. After three months of daily use across hardwood floors, thick carpet, and tiled bathrooms, it’s not. It’s the most thorough clean we’ve achieved with a cordless vacuum, period.

Suction & Performance

The 240 AW suction (the most powerful Dyson has ever produced in a stick vacuum) handles everything from fine dust to large debris without a single pass-over. On carpet, the green laser highlights pet hair and dust in the pile that standard lighting hides entirely. The automatic suction adjustment — it boosts power when more particles are detected — means you’re not guessing at settings.

The LCD particle counter is legitimately useful. Watching the count drop as you complete a pass provides satisfaction and a clear signal when an area is genuinely clean.

Battery & Runtime

60 minutes on Eco mode; 15 minutes on Boost. In practice, a full flat clean (3 bedrooms, kitchen, living room) on Auto mode ran 38 minutes and finished with battery to spare.

Expensive, but it earns the price. The laser reveal and particle counter aren’t marketing — they fundamentally change how you clean. If you’re buying one vacuum to last a decade, the V15 Detect is it.
