Frequently Asked Questions
How often should Shark vacuum filters be cleaned?
Shark recommends cleaning the foam and felt filters once a month. The HEPA post-motor filter should be rinsed every 3 months and replaced annually.
Why does my Shark lose suction on carpet but not on hard floors?
On carpet, a clogged or hair-tangled brush roll adds resistance. Check the brush roll as well as the filters. The brush roll indicator light may also be red.
Can I use my Shark vacuum while the filter is drying?
No — using the vacuum without a fully dry filter will damage the motor and push dirty air back into the room. Allow a full 24-hour drying time.
