- Use a long, narrow crevice tool to carefully remove dust or hair trapped in the nozzle, brush bar, or internal passages.
- Ensure all parts are clear before reassembling the vacuum.
Examine the Battery and Power Settings

- Check if the power trigger is being pressed steadily and correctly. Avoid holding it down for extended periods if it’s a power mode issue.
- If pulsing persists, consider the battery’s age and health. A degraded battery might cause inconsistent power delivery.
Perform a Reset and Test
- Turn off the vacuum and remove the battery (if removable).
- Wait for a few minutes, then reassemble the battery and power on the vacuum.
- Test the vacuum on different surfaces or with different power modes to see if pulsing continues.
