Do bladeless fans use more electricity than regular fans?

They're comparable — most bladeless fans use 30-60W, similar to traditional tower fans. Dyson models with purification may use slightly more when actively filtering.

How do bladeless fans actually work?

They use a brushless motor in the base to draw air in and accelerate it through a narrow aperture in the loop, creating a smooth stream of air via the Coanda effect.
