  1. Remove the pre-filters and main filters from your Dyson vacuum.
  2. Rinse the filters with cold water, then wring out excess water.
  3. Allow filters to dry completely for at least 24 hours before reinstalling.
  4. Replace filters if they are heavily stained or worn out.

2. Inspect the Cleaner Heads and Attachments

  • Detach the Digital Motorbar or Fluffy Optic cleaner head and check for hair or debris tangled inside.
  • Use a small tool or your fingers to remove any obstructions.
  • Ensure the brush bar spins freely and no parts are damaged.

3. Test the Battery and Charging Process

  • Charge your vacuum fully in a standard outlet, avoiding extension cords.
  • Monitor the charging indicator; ensure it shows a complete charge.
  • If the battery still drains quickly after full charge, consider replacing it.

If your vacuum’s battery no longer holds a charge or drains rapidly despite cleaning and maintenance, replacing the battery may be necessary. Contact Dyson support or an authorized service center for compatible replacement batteries.

5. Update Firmware and Reset Vacuum

If your Dyson V15 Detect™ Origin has an LCD screen, check for firmware updates via the Dyson app or support site. Reset the vacuum by turning it off, removing the battery, waiting a few minutes, and then reinserting the battery to reset internal systems.
