Operating Guidelines
Selecting the correct filter for your cleaning task is essential for effective operation and filter longevity.
Dry Pickup Operations
- Use the 90671 disposable filter bags for collecting most dry debris, including sawdust, drywall dust, and general dry garbage. These bags offer convenient disposal and prevent secondary pollution.
- The 90107 paper disc filters are also suitable for dry pickup. They should be used with a retain band over the filter cage.
- The filter system is designed to capture at least 99.97% of particles, ensuring a cleaner environment.
Wet Pickup Operations
- For wet pickup, use the 90585 foam sleeve filter. This filter is designed to handle liquids and can be reused after cleaning.
- Do not use disposable filter bags or paper disc filters for wet pickup, as they are not designed for liquids and can be damaged.

Maintenance
Regular maintenance of your filters ensures consistent vacuum performance and extends the life of your appliance.
Filter Bag (90671) Disposal
- When the filter bag becomes full, unplug the vacuum.
- Remove the power head and carefully lift out the full bag.
- Dispose of the bag and its contents in a waste receptacle. This method minimizes dust exposure.
- Install a new filter bag as per the setup instructions.
Paper Disc Filter (90107) Replacement
- Unplug the vacuum and remove the power head.
- Carefully remove the retain band and the used paper disc filter.
- Dispose of the used filter.
- Install a new paper disc filter and secure it with the retain band.
Foam Sleeve Filter (90585) Cleaning
- Unplug the vacuum and remove the power head.
- Carefully slide the foam filter off the filter cage.
- Rinse the foam filter thoroughly under running water until clean.
- Allow the foam filter to air dry completely before reinstalling it. Reinstalling a wet foam filter for dry pickup can damage the vacuum.
General Replacement Recommendation
It is recommended to replace disposable filter elements (bags and paper discs) every 4-5 months, or more frequently depending on usage and the type of debris collected, to maintain optimal vacuum performance.
Troubleshooting
If your Shop-Vac experiences reduced suction or unusual operation, consider the following troubleshooting steps related to the filter kit:
- Reduced Suction: Check if the filter bag is full or if the paper disc filter is clogged. Replace or clean as necessary. Ensure the foam filter is clean and dry if used for wet pickup.
- Dust Escaping: Verify that all filters are correctly installed and sealed. Ensure the filter bag's collar is securely over the inlet port and the retain band is holding the paper disc filter firmly.
- Motor Overheating: A severely clogged filter can cause the motor to work harder. Replace or clean filters promptly to prevent overheating.
Always ensure the vacuum is unplugged before performing any inspection or maintenance.
