Operating Instructions

The FLYLINKTECH V6 replacement battery operates identically to the original Dyson battery. Simply press the power trigger to start and release to stop. For optimal battery life and performance, consider the following:

  • Standard Mode: For everyday cleaning tasks, using the standard power mode is recommended to maximize operating time.
  • MAX Mode: The MAX power mode provides increased suction for tougher cleaning but will significantly shorten the battery's run time. Use this mode only when necessary.
  • Charging: Always ensure the battery is fully charged before extensive use.

Maintenance

Proper maintenance will extend the life of your battery and vacuum cleaner.

  • Battery Cooling: Do not charge the battery immediately after it has been depleted, especially after using MAX mode. Allow the battery to cool down for 10 to 20 minutes before charging. This is crucial for battery longevity.
  • Filter Cleaning: The included V6 replacement pre-filters are washable and reusable. Regularly clean the filters according to your vacuum cleaner's instructions to maintain optimal suction and prevent strain on the battery.
  • Storage: If storing the vacuum for an extended period, ensure the battery is partially charged (around 50%) and store it in a cool, dry place.
