Maintenance
Regular maintenance of the main body and its filter system is crucial for maintaining optimal performance and extending the life of your vacuum.
1. Filter Cleaning and Replacement
The main body houses the vacuum's filter. Regular cleaning prevents loss of suction.

- Ensure the vacuum is off and the dust bin is removed.
- Locate and remove the filter assembly from the main body.
- Tap the filter gently over a trash can to remove loose dirt and debris.
- If the filter is washable (check your original vacuum manual), rinse it with cold water until the water runs clear. Allow it to air dry completely for at least 24 hours before reinstallation. Do not use a hairdryer or other heating methods.
- Replace the filter assembly back into the main body, ensuring it is securely seated.
- Replace filters as recommended by Shark, typically every 3-6 months, depending on usage.
2. Exterior Cleaning
- Wipe the exterior of the main body with a soft, damp cloth.
- Do not use abrasive cleaners or solvents, as these can damage the surface.
- Ensure no moisture enters the electrical components or charging port.
3. Battery Care
- To maximize battery life, avoid fully discharging the battery frequently.
- Store the vacuum in a cool, dry place when not in use.
- If storing for an extended period, charge the battery to approximately 50% before storage.
