Step 2: Check for Blockages and Obstructions

  1. Remove the cleaner head and inspect the hose and wand for debris or blockages.
  2. Clear any visible obstructions carefully.
  3. Reattach the cleaner head securely.

Step 3: Clean or Replace Filters

Dirty filters can cause the vacuum to pulse due to reduced airflow. Remove the filters from the vacuum, rinse them with water, and let them air dry completely for 24 hours. If filters are damaged or worn, replace them with compatible spare filters.

Step 4: Inspect the Battery and Connections

Check that the battery is properly seated and connections are secure. If you notice any corrosion or loose wires, gently reconnect or replace faulty parts. A faulty battery or loose connection can cause inconsistent power, leading to pulsing.

Step 5: Verify Attachments and Brush Heads

Ensure that the brush head and other attachments are clicked in securely. Remove any tangled hair or debris from the brushes, as obstructions can affect suction and trigger pulsing behavior.
