Step 1: Power Off and Unplug

Before starting any troubleshooting, turn off the vacuum and unplug it if it is charging. This ensures safety and prevents accidental activation during inspection.

Step 2: Check for Blockages

  1. Remove the cleaner head and inspect for debris or hair that might be clogging the airflow.
  2. Check the wand and extension tubes for obstructions.
  3. Clear any blockages carefully, ensuring nothing is stuck in the nozzle or hose.

Step 3: Clean or Replace Filters

Dirty filters can cause the vacuum to pulse as airflow is restricted. Remove the pre-filter and main filter from the vacuum. Rinse the filters with water and let them air dry completely for at least 24 hours before reinstalling. If filters are damaged or very worn, replace them with compatible filters.

Step 4: Check Battery and Connections

Ensure the battery is securely connected. If your vacuum has a removable battery, take it out and reinsert it firmly. Inspect for any damage or corrosion on connections. If the battery shows signs of failure, consider replacing it with a compatible one.

Step 5: Reset and Test

  1. After cleaning filters and checking connections, turn the vacuum back on.
  2. Run the vacuum on different floor types and power modes to see if the pulsing persists.
  3. If the issue remains, perform a reset if your model supports it (refer to the manual).
