Learns over time
The Dyson V11™ battery and monitoring system work together to gauge how much run time is remaining.
This is then displayed on the machine's LCD screen. The system calculates displayed run time using an algorithm that ‘learns’ how your machine works over time, with the algorithm increasing in accuracy with use. The actual run time of your machine remains unaffected while the algorithm learns to more accurately gauge remaining power.
Charging your vacuum
It's important to fully charge the machine before using it for the first time, and after every clean. This helps to improve the algorithm's accuracy. The battery is designed to be left on charge permanently, and this will ensure that the vacuum is fully charged when it's next used. Once the battery is fully charged, your machine won't use any more electricity
All batteries differ and may vary during their lifetime. Run time can be affected by the cleaning mode you use and the different power draw on varied surfaces – long-pile carpets will draw more power than short pile, for example. In addition, all batteries naturally differ slightly from one another, affecting the amount of power they can produce.
