When and how do I clean the filters?

Filters may need to be cleaned if the vacuum stops picking up dirt, if airflow is restricted, or if you notice lighter or no suction. For optimal performance, clean filters regularly. Between cleanings, lightly tap filters over a trash receptacle to remove dust and debris as needed. Rinse the pre-motor foam and felt filters every 3 months, or as needed.

  3. Remove the foam and felt filters.
  4. Rinse both filters with water only.
  5. Allow filters to air-dry completely (at least 24 hours) before reinstalling.
  6. Once dry, replace the felt filter first, followed by the foam filter.
  7. Reinstall the dust cup by placing the bottom of dust cup into the pod and then tilting until it clicks into place. Rinse the post-motor HEPA filter every 12 months, or as needed.
  8. Pull the latch under the HEPA filter cover and lift off the cover.
  9. Remove the HEPA filter.
  10. Rinse with water only.
  11. Allow filter to air-dry completely (at least 24 hours) before reinstalling.
  12. Once dry, reinstall the HEPA filter.
  13. Reattach the HEPA filter cover until it clicks into place.
How and when do I adjust the suction?

Slide the suction control button at the end of the hose forward to reduce suction for more maneuverability on carpets. For more suction for cleaning bare floors or using accessories, slide the button back.
