Check and Clean the Filters
- Turn off and unplug your Dyson V15 Detect™ vacuum. Remove the pre-filters located at the cyclone or dustbin area. These filters are usually easy to access by twisting or pulling them out.
- Rinse the filters thoroughly under cold water. Use your fingers or a soft brush to remove stubborn dust or debris. Avoid using detergents or soaking for extended periods.
- Allow the filters to air dry completely, ideally for at least 24 hours, before reinstalling. Well-dried filters ensure optimal suction and prevent airflow issues that cause pulsing.
- Reassemble the vacuum and test it. If pulsing persists, proceed to the next step.

Inspect the Battery and Power Settings
Ensure your vacuum’s battery is adequately charged. A low or faulty battery can cause intermittent power delivery, leading to pulsing. Connect the vacuum to the charger and let it fully charge for at least 3 hours.
Check the power mode displayed on the LCD screen. The vacuum intelligently adapts power based on debris detection, but if settings are incorrect or the mode is malfunctioning, it could cause pulsing. Switch between modes to see if stability improves. If issues continue, consider replacing the battery or contacting Dyson support.
Examine for Internal Blockages or Obstructions
Blockages in the wand, cleaner head, or internal passages can disrupt airflow, causing the vacuum to pulse. Detach the cleaner head and check for tangled hair, debris, or obstructions. Use a long, flexible tool or the crevice attachment to clear narrow passages.
Inspect the wand and hose for any clogs. Remove and rinse if necessary, ensuring no debris remains inside. Proper airflow is essential for consistent suction and operation.
Verify Attachments and Fitment
Ensure all attachments, especially the cleaner heads and crevice tools, are correctly fitted and compatible with your model. Improper attachment or incompatible accessories can trigger sensors that cause pulsing.
Remove any non-compatible or loose attachments, then reattach securely. If you use a third-party accessory, verify its compatibility with the Dyson V15 Detect™ Origin.
Reset and Test the Vacuum
- Turn off the vacuum and disconnect it from the charger.
- Press and hold the power button for about 10 seconds to reset the electronic system.
- Reconnect to the charger and turn it on to see if the pulsing issue is resolved.
- If pulsing persists, consider performing a full system reset or contacting Dyson support for advanced troubleshooting.
