Installation Instructions
Replacing the brushroll in your Shark Navigator Lift-Away vacuum requires careful disassembly and reassembly of certain vacuum components. It is highly recommended to consult your specific vacuum model's original instruction manual or search for detailed video tutorials online for visual guidance. Ensure the vacuum cleaner is completely unplugged from the power outlet before beginning any installation or maintenance procedures.
- Safety First: Unplug your Shark Navigator Lift-Away vacuum cleaner from the electrical outlet.
- Access the Brushroll Housing: Carefully turn the vacuum cleaner over to access the brushroll housing. Depending on your model, this may involve removing screws or latches. Some models may have 'hidden' screws, so refer to your vacuum's specific manual or online guides.
- Remove the Old Brushroll: Once the housing is open, carefully lift out the old brushroll. Note the orientation of the end caps and any associated gears or belts.
- Inspect the New Brushroll: Before installation, inspect the new Pildres brushroll for any damage or missing components. Ensure both end pieces are securely attached.
- Install the New Brushroll: Place the new brushroll into the housing, ensuring it aligns correctly with the belt (if applicable) and the end caps fit into their designated slots.
- Reassemble: Securely close the brushroll housing, ensuring all screws or latches are fastened.
- Test: Plug in the vacuum and test the brushroll to ensure it spins freely and operates correctly.

Operating the Brushroll
Once the Pildres replacement brushroll is correctly installed, it operates automatically as part of your Shark Navigator Lift-Away vacuum cleaner. Ensure that the vacuum is turned on and the brushroll function is engaged (if your model has a separate control) for optimal cleaning performance on carpets and hard floors.
Before each use, quickly check the brushroll area for any large debris that could obstruct its rotation or cause damage.
Maintenance and Care
Regular maintenance of your brushroll is crucial for extending its lifespan and ensuring consistent cleaning performance. Always unplug the vacuum before performing any maintenance.
- Debris Removal: Periodically inspect the brushroll for tangled hair, threads, pet fur, and other debris. Use scissors or a seam ripper to carefully cut and remove any tangled material from the bristles and around the brushroll ends.
- Bristle Inspection: Check the bristles for wear. If they are excessively worn, flattened, or missing, it may be time to replace the brushroll to maintain effective agitation and cleaning.
- End Cap Check: Ensure the brushroll's end caps are clean and free from debris that could impede rotation.
- Cleaning: The brushroll itself can be wiped clean with a damp cloth. Avoid submerging it in water.

Troubleshooting
If you encounter issues with your Pildres replacement brushroll, consider the following troubleshooting steps:
- Brushroll Not Spinning:
- Ensure the vacuum is unplugged. Check for any large obstructions (e.g., socks, toys) jammed in the brushroll area.
- Remove any tangled hair or debris from the brushroll and its end caps.
- Verify that the brushroll is correctly seated in its housing and that the vacuum's drive belt (if applicable) is intact and properly aligned.
- Reduced Cleaning Performance:
- Inspect the brushroll bristles for excessive wear. Worn bristles will not agitate carpets effectively.
- Ensure the vacuum's filters are clean and the dust cup is empty, as these can affect overall suction.
- Unusual Noises:
- Unplug the vacuum. Check the brushroll for any foreign objects caught within the bristles or housing.
- Ensure the brushroll is installed correctly and not rubbing against any part of the vacuum housing.
If problems persist after following these steps, refer to your Shark Navigator Lift-Away vacuum's main user manual or contact customer support.
