To clean a Shark Rotator’s reusable foam or felt filter, remove the dust cup from the vacuum, and remove and rinse the filter under running water. To clean a Rotator HEPA filter, wash the filter by hand. Allow the filter to dry completely before replacing it, and then replace the dust cup. The filter should slide right out of the dust cup; to replace it, slide it back in the same position.
The Shark Rotator comes with a reusable on-board filter that the owner cleans according to the cleaning schedule recommended by Shark. Rotators equipped with foam or felt filters require cleaning every three months, while those models with HEPA filters require cleaning every 12 months. Shark recommends tapping Rotator filters regularly over the edge of a trash can to remove debris between washes as needed.
A dirty filter on the Shark Rotator may cause issues that require troubleshooting. If a Shark Rotator loses suction or if suction is light, check the filter to see if it requires cleaning. Rinse the filter, allow it to dry, and reinsert the filter. If the unit powers on spontaneously, the vacuum may have overheated. In this case, a dirty filter may be to blame. Clean the filter as part of the troubleshooting process.
