- Inspect the wand and hose for clogs or debris buildup.
- Clear any obstructions carefully, ensuring the airflow path is open.
Step 3: Clean or Replace the Filters
- Remove the pre-filters and filters from your vacuum as per the user manual.
- Wash the filters with cold water and let them air dry completely for at least 24 hours.
- Reinstall the filters securely, or replace with a new set if they are very dirty or damaged.
Step 4: Check the Battery and Power Mode
Ensure the battery is charged and seated properly. If your vacuum has different power modes, switch to a lower mode to see if pulsing persists, indicating a power supply issue.
Step 5: Test and Reset the Vacuum
Reassemble all parts and turn on the vacuum. Test in a controlled area. If pulsing continues, perform a reset by turning off, removing the battery (if removable), waiting a few seconds, then reinserting and powering on.
