Learns over time

The Dyson V11™ cordless vacuum cleaner 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 vacuum works over time, with the algorithm increasing in accuracy with use. The actual run time of your cordless vacuum remains unaffected while the algorithm learns to more accurately gauge remaining power.

The system calculates run time using an algorithm that ‘learns’ how your machine works over time. This could mean that initial run times shown may not reach the figures quoted while the algorithm adjusts to the battery. As it learns, however, it will more accurately gauge how much power remains.

Charging your cordless vacuum

It's important to fully charge the vacuum 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 cordless vacuum won't use any more electricity.

Battery performance

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.

You can help preserve the run time and overall life of your battery by using the power mode best suited to your cleaning task, and only using Boost mode for intensive cleaning.
