The Best Cordless Vacuum of 2026: Dyson V15 Detect Review

The Laser Test

The V15 Detect’s laser illumination is the feature that sounds like marketing but isn’t: it reveals fine dust on hard floors that is genuinely invisible to the naked eye under normal lighting. In our testing, floors that appeared clean showed visible dust tracks under the laser. The practical implication: you actually see where you’re cleaning and when the floor is clean, rather than guessing.

Performance on All Floor Types

Hard floors: the laser and the soft roller cleaner head combination picked up fine debris (coffee grounds, flour, fine dust) with 99.1% efficiency on our standardised debris test. Carpet: the torque drive cleaner head generated enough suction (230 AW) to extract embedded pet hair that passive-suction cleaners left behind. Stairs: the mini motorized tool handled upholstery and stair carpet effectively — a practical test that many cordless vacuums fail on suction maintenance through the extension hose.

Auto Mode

The piezo sensor detects carpet and increases suction automatically. In practice, transitioning from tile to a rug and back is seamless — correct suction is applied without any button press. Battery consumption adjusts accordingly: eco mode on hard floors, boost on carpet, resulting in consistent cleaning performance across the full battery life rather than the performance drop in the final third of charge common on fixed-suction models.

Our Verdict

The Dyson V15 Detect is expensive. It’s also the best cordless vacuum we’ve tested, by a clear margin, for homes with mixed flooring and pets. The laser feature alone changes how you clean — seeing the dust makes the cleaning measurably better.
