Hi there, this is Krystal with Dyson. Thank you for your interest in the Dyson Cyclone V10. This vacuum has a trigger that must be held to provide power. The Dyson range of cordless vacuum cleaners has a battery-enhancing trigger. Battery power is only on when the trigger is pushed – this means that the battery is only used for cleaning, and is not wasted when moving from room to room, or moving around obstacles.
