The Dyson V15 Detect is Dyson’s flagship cordless vacuum. After 30 days of testing, here’s what we think.
What Makes It Special
The laser. A green laser on the front illuminates dust particles on hard floors that are invisible to the naked eye. It sounds like a gimmick ?it’s not. You’ll be horrified at how much dust you’ve been missing.
Suction Power
240 AW on boost mode ?the strongest cordless vacuum Dyson has ever made. In practice:
- Hard floors: Flawless
- Low-pile carpet: Excellent
- Medium-pile carpet: Very good
- Thick carpet: Good (not as good as a corded upright)
The Piezo Sensor
A built-in sensor counts and sizes particles, displaying a live graph on the LCD screen. It automatically increases suction when it detects more debris. Useful? Yes. Game-changing? Not really.
Battery Life
- Eco mode: 60 minutes
- Auto mode: 30-40 minutes
- Boost mode: 8-10 minutes
For most homes, auto mode is enough for a full clean. The battery is swappable (buy a spare for $100).
Weight & Ergonomics
6.8 lbs. Heavier than the V12 (5.2 lbs) but balanced well. Your arm won’t tire during a 30-minute session. The trigger button is comfortable.
Filtration
Whole-machine HEPA filtration captures 99.97% of particles. The filter is washable ?rinse it monthly and let it dry for 24 hours.

Who Should Buy?
?You have hard floors (the laser is most useful here) ?You want the strongest cordless suction ?You have allergies (HEPA filtration) ?You want a premium, well-built machine
Who Should Skip?
?You’re on a budget (the V12 is $200 cheaper and 90% as good) ?You only have carpet (laser doesn’t work on carpet) ?You need 60+ minute runtime regularly
Verdict
The Dyson V15 Detect is the best cordless vacuum you can buy. The laser genuinely changes how you clean. But if you’re budget-conscious, the V12 Detect Slim offers 90% of the experience for $200 less.
Rating: 4.7/5 ⭐⭐⭐⭐?
FAQ
Is the Dyson V15 Detect worth the price?
If you have hard floors, yes ?the laser feature alone justifies the premium. For carpet-only homes, the V12 or a Shark is better value.
How long does the Dyson V15 battery last?
30-40 minutes on auto mode, 60 minutes on eco, 8-10 minutes on boost. Battery is replaceable and costs about $100.
Can the Dyson V15 replace a corded vacuum?
For most homes, yes. It has enough power and battery life for a full clean. Very large homes (3,000+ sq ft) may need a spare battery.
