  3. Clear out any obstructions using a long, flexible brush or compressed air.

Step 3: Clean or Replace Filters

  1. Remove the pre-filters and main filters as per the user manual.
  2. Wash the filters with water, ensuring they are fully dry before reinstalling (about 24 hours).
  3. If filters are damaged or excessively dirty, replace them with compatible filters, such as the 3Pack Pre Filters Replacement.

Step 4: Check the Battery and Connections

Ensure the vacuum is fully charged. Remove the battery pack if possible and inspect the contacts for dirt or damage. Reassemble securely.

Step 5: Reset and Test the Vacuum

After cleaning and checking components, turn on the vacuum. If it still pulses, let it cool down for 15-30 minutes and try again. This can reset overheating protection.
