Clean or Replace Filters

  • Remove the pre-filters and main filters from your Dyson V15.
  • Wash the filters with water and let them air dry completely—do not use heat.
  • If filters are worn out or excessively dirty, replace them with compatible options like the 3Pack Pre Filters Replacement or V10 Filters.

Optimize Usage and Charging Habits

  • Avoid leaving the vacuum on maximum power mode unnecessarily—use eco mode when possible.
  • Charge the vacuum fully before each use, avoiding partial charges or overcharging.
  • Allow the battery to fully discharge before recharging if recommended by Dyson.

Update Firmware and Perform Maintenance

Check the LCD screen for any maintenance alerts or error messages and follow prompts to reset or update firmware if available. Regularly clean the cleaner heads and brush bars to reduce motor strain and battery drain.

Consider Battery Replacement

If all other steps fail and your battery still drains quickly, replacing the battery may be necessary. Use genuine Dyson batteries or compatible options like the LANMU Crevice Tool compatible with your model.
