What stands out
- Laser head reveals invisible fine dust
- Strongest measured cordless suction
- Intelligent power management
- Satisfying real-time particle display
Watch-outs
- Expensive
- Heavy for one-handed use
- Battery not user-replaceable
The Dyson V15 Detect comes close to making vacuuming exciting. The combination of the green laser head, the acoustic particle sensor that counts debris in real-time, and the strongest measured suction of any cordless vacuum we’ve tested makes this a genuinely different product.
Laser Head
The angled green laser illuminates fine dust on hard floors that is genuinely invisible without it. Once you have used it, you cannot go back to a standard floor head. It is that effective at revealing what you would otherwise miss.
Suction Performance
On max mode, the V15 has the strongest measured suction of any cordless vacuum in our tests. It handles dense carpet, hard floors, and pet hair on upholstery without hesitation or multiple passes.
Battery Runtime
We measured 42 minutes in standard mode — enough for most homes in a single charge. The intelligent power management adjusts suction automatically based on what the sensors detect on the floor surface, extending runtime when cleaning is easy.
