3 Things to Know About the Dyson V12 Detect Slim's Battery Life

On low power, the battery lasts up to 40 minutes. This is enough to clean a small apartment in one pass.

On auto mode, runtime drops to about 25 minutes. That mode adjusts suction based on floor type, which drains the battery faster.

For anything larger than a small apartment, keep the Dyson charger nearby. You will likely need to recharge before finishing a full cleaning session.
