What I see on a daily basis for the 4 modes
- Eco = 45mn
- Eco+ = 30mn
- Power = 17 minutes
- Max = 9mn (but I never use it except on encrusted carpets..)

I strongly advise against this hoover, the battery life is less than indicated, the suction is not nearly as good as mentioned as well. I regret my purchase very much!
