v11 vs v15

 

The Dyson V15 is a more powerful and advanced vacuum than the V11, featuring higher suction power (240AW vs 185AW),a laser to show hidden dust, and a particle sensor that automatically adjusts suction. The V11 has a longer battery life on low power, while the V15 is better for deeper cleaning due to its increased suction. Key differences include the V15's laser and particle sensor, while they share features like a 60-minute maximum runtime, a 2-in-1 design, and a washable filter.
