Inspect and Clean Filters

  1. Remove the pre-filters and any other filters according to the user manual.
  2. Rinse reusable filters (like the 3Pack Pre Filters or V10 filters) with water and let them dry completely before reinstalling.
  3. Replace filters if they appear damaged or excessively clogged.

Evaluate Power Settings and Usage

  • Ensure you’re using the appropriate power mode for your cleaning task, as higher modes consume more battery.
  • Use the power trigger efficiently—only activate when necessary to conserve energy.
  • Check the LCD screen for alerts or remaining run time to adjust your usage accordingly.

Ensure Proper Charging Practices

  1. Use the original Dyson charger and avoid leaving the vacuum plugged in continuously after full charge.
  2. Charge in a cool, dry place and avoid partial or interrupted charging cycles.
  3. If the battery does not seem to charge fully, consider replacing the charger or battery.

Replace Worn or Damaged Parts

  • Replace filters regularly—every 2-3 months—to maintain suction and prevent motor strain.
  • Consider replacing the battery if runtime remains short despite proper maintenance.
  • Use compatible accessories like the LANMU Crevice Tool for thorough cleaning, which reduces strain on the vacuum.
