Replace or Clean Filters

  • Remove the pre-filters and main filters from your Dyson vacuum.
  • Rinse the filters thoroughly with water and let them air dry completely (at least 24 hours).
  • Reinstall the filters securely once dry.
  • Dirty filters can cause the motor to work harder, leading to faster battery drain.

Optimize Charging Habits

Always use the original charger provided with your Dyson V15 and avoid leaving the vacuum on charge for extended periods after it’s fully charged. Aim to keep the battery between 20% and 80% for longevity. Avoid letting the battery completely discharge or stay at 0% for long durations.

Adjust Power Settings

Use the LCD screen to select the appropriate power mode for your cleaning task. Lower power modes conserve battery and are sufficient for hard floors and light debris. Reserve high power modes for deep cleaning, and switch back to save battery life.

Maintain Attachments and Accessories

Check that all attachments, such as the crevice tool, are in good condition and compatible. Damaged or incompatible tools can cause increased resistance, leading to quicker battery depletion.
