Step 2: Check for Clogs and Blockages
- Remove the wand and cleaner head from the vacuum.
- Inspect the wand, hose, and cleaner head for debris or blockages.
- Clear any obstructions gently using a long, flexible brush or cloth.
Blockages restrict airflow, which can cause the pulsing issue.
Step 3: Clean or Replace Filters
Dirty filters can impair suction and cause pulsing. Remove the pre-filter and main filter according to your model’s instructions.
- Wash the filters with cold water, avoiding soaps, and allow them to air dry completely (at least 24 hours).
- If filters are damaged or excessively dirty, replace them with new ones (see recommended filters below).
Step 4: Verify Battery and Power Settings
Ensure the battery is properly connected and charged. If the vacuum still pulses, consider resetting the power mode or performing a battery check if accessible. Consult your user manual for specific reset instructions.
Step 5: Reset and Test
Reassemble all parts, turn on the vacuum, and test on a clean surface. If pulsing persists, proceed with further inspection or contact Dyson support.
