Dyson V15 Detect Vacuum

The Dyson V15 Detect has a laser in the cleaning head that shows you dust particles on a hard floor by illuminating them with a green light angled at 1.5 degrees. Seeing the dirt you couldn't see before changes how you think about cleaning entirely. Suction adjusts automatically based on what the sensors detect, and a small screen on the back shows a real-time count of particle sizes it's picking up. At $750 it better work well, and it does. Battery lasts about 60 minutes on the lowest setting and the bin is clear so you can see exactly what you collected. Clean floors and a visible bin of evidence at the end — that's what $750 buys you.
