Inspect and Clean the Filters
- Remove the pre-filters and main filters from the vacuum according to the user manual.
- Wash the filters with water, ensuring they are completely dry before reinstalling. Use the 3Pack Pre Filters Replacement or Replacement V10 Filters if needed.
- Dirty or clogged filters can restrict airflow, causing the vacuum to pulse as it struggles to maintain suction.
Check for Blockages and Obstructions
- Inspect the cleaner head and wand for debris or tangled hair that could impede airflow.
- Remove and clear any blockages from the wand, cleaner head, and crevice tools.
- Ensure the brush bar spins freely and is free of debris or hair entanglements.
Examine the Sensor and Motor
- Ensure there are no obstructions blocking the sensor area, especially on the digital display or sensors near the cleaner head.
- If the vacuum has been dropped or impacted, check for loose parts or damage to the motor or sensor components.
- Contact Dyson support if you suspect a faulty sensor or motor issue that cannot be visually inspected or fixed at home.
Additional Maintenance Tips
Regularly replace filters with compatible options such as the 3Pack Pre Filters Replacement or V10 Filters to maintain optimal airflow and suction. Keep the brush bar clear of hair and debris. Periodically check the battery connections if pulsing continues after cleaning.
