⭐ Our Verdict

The Dyson V15 is the best cordless vacuum for data-driven cleaners. The laser and particle counter are genuinely useful - they changed how I clean. But at $750, the Shark Stratos at $400 delivers 90% of the performance.

✅ Pros

✓Laser reveals dust you cannot see
✓Piezo sensor counts and displays particle sizes
✓60-minute battery covers whole house
✓LCD screen shows remaining runtime
✓Anti-tangle brush bar actually works

⚠️ Cons

✗$750 is $300 more than Shark Stratos
✗Heavy at 6.8 lbs for extended above-floor use
✗Battery not swappable (can buy spare for $150)
✗Dust bin is small needs frequent emptying

The Dyson V15 Detect laser revealed a disturbing amount of dust on my supposedly clean floors. The particle counter showed thousands of microscopic particles per sweep. Now I cannot go back to a regular vacuum.

Laser vs Regular Vacuum

The green laser (angled at 1.5 degrees) reveals dust invisible to the naked eye. I vacuumed my living room with my old vacuum, then ran the Dyson. The dust bin was half full. That laser is not a gimmick.

Best Price

$749 on Amazon. Dyson refurbs at $499 with warranty.
