Dyson V15 Detect vs V8 Cyclone

The higher-end Dyson V15 Detect is unsurprisingly a better vacuum than the more budget-friendly Dyson V8 Cyclone. It cleans better on almost every surface, picking up more debris on bare floors and carpet, and clearing deep cracks more easily. It also adjusts suction automatically, shines a light across hard floors to illuminate fine dust, and has a sensor that tracks how much dust it picks up. The V15's dustbin is bigger, so you'll empty it less often. The Cyclone is slightly lighter overall and has a push button, while the V15 makes you hold a trigger as you clean.
