Dyson’s V15 Detect Hunts Dirt with Laser Vision

Equipped with a laser to detect hidden dirt and particles that your eye can’t see, Dyson’s V15 Detect cordless vacuum is a home appliance purpose-built for the clean freak. In addition to its dirt-spotting laser, it uses a piezoelectric sensor to log data on the amount and size of the dirt it picks up—which it displays on its LCD screen.
