Step 2: Clean or Replace the Filters
- Remove the filters as per the user manual—use the replacement filters if yours are dirty or worn.
- Rinse the filters under cold water until clear, then let them air dry completely (at least 24 hours).
- Reinstall the filters securely after drying.
Step 3: Check and Reset the Sensors
Dirty sensors can cause the vacuum to pulsing. Use a soft, dry cloth to gently wipe the sensors located near the cleaner head and inlet areas. Ensure contacts are dry and free from dust or debris.
If your model has a reset button, press it to recalibrate the sensors, following the user manual instructions.
Step 4: Verify Battery and Power Connections
Ensure the battery is properly seated and the contacts are clean. If you notice corrosion or dirt, clean with a dry cloth. Reconnect the battery securely.
Test the vacuum again to see if the pulsing issue persists.
Additional Tips and Warnings
- Always disconnect from power before inspecting or cleaning internal components.
- Use only recommended filters and attachments to avoid damage.
- Do not immerse electrical parts in water or use harsh chemicals.
