Step 2: Clean or Replace Filters

  • Remove the pre-filter and other filters as per your model’s manual.
  • Rinse filters with water and let them dry completely before reinstalling.
  • If filters are worn or excessively dirty, replace them with compatible replacements like the 3Pack Pre Filters or V10 Filters.

Step 3: Check and Update Firmware

Connect your vacuum to the Dyson app or follow the manufacturer’s instructions to see if firmware updates are available. Updating can optimize battery usage and overall performance.

Step 4: Optimize Usage and Charging Habits

  • Avoid letting the battery fully discharge frequently, as this can shorten its lifespan.
  • Charge the vacuum in a cool, dry place and disconnect once fully charged.
  • Use the power modes efficiently; switch to lower power on hard floors to conserve battery.

Step 5: Consider Battery Replacement

If all else fails and your battery still drains quickly, replacing it with a genuine or compatible replacement is your best option. Follow the manufacturer’s instructions or seek professional help to ensure safe installation.
