The system does work and we observed plenty of dirt we'd normally miss. Its purpose is to highlight dust and other small bits of debris otherwise hard to spot with the naked eye.

Designed for hard flooring, it shines a green laser out onto the floor ahead as you clean. One is the vacuum's Laser Slim Fluffy cleaner head. The V15 is a great cordless vacuum for pet hair, too: No matter if it was vacuuming across hardwood, low-pile, or midpile carpeting, the V15 barely left a tuft in its wake.Ī few other features help set the V15 Detect apart. That's a lot better than the 78.4% the V11 was able to muster here. More impressively, the V15 pulled 95.3% of sand particles we dropped onto low-pile carpeting. It was able to remove 88.4% of test sand we placed on midpile carpeting. The V15 also achieved these cleaning performance results on our most difficult trial, sand. The V15 demonstrated more suction power than the Dyson V11, the previous cordless vacuum champion. This cordless stick vacuum didn't just outperform competitors from other brands. Like its predecessor the V11, the V15 ripped through our suite of vacuum cleaner tests with ruthless competence. It's by far the most expensive machine in our test group. As the company's flagship cordless vacuum, the V15 has a sky-high price to match. Say hello to the best Dyson cordless vacuum, the $750 Dyson V15.
