Shark NV352 user manual

The location of the brush bar reset button on Shark vacuums can vary depending on the specific model. However, on many Shark vacuum models, the brush bar reset button is typically located on the main vacuum head, near the brush roll itself. Here's a step-by-step guide on how to locate and use the brush bar reset button:
1. Ensure the vacuum cleaner is powered off and unplugged for safety.
. Flip the vacuum cleaner over so that you can access the brush roll area.
3. Look for a small button or switch near the brush roll, usually labeled as "brush roll," "brush roll reset," or with a brush roll icon.
4. Press or slide the reset button/switch to disengage the brush roll and reset it.
5. Make sure the brush roll spins freely after resetting it.
6. Once the brush roll is reset, you can plug in the vacuum and turn it back on to resume cleaning.
If you're having trouble locating the reset button on your specific Shark vacuum model, it's recommended to consult the user manual or contact Shark customer support for assistance.

There could be several reasons why the brush on your Shark NV352 lift away vacuum cleaner is not spinning. Here are some possible causes and troubleshooting steps to try:
1. Brushroll obstruction: Check if there are any hair, fibers, or debris wrapped around the brushroll. If there is an obstruction, remove it carefully, making sure to turn off and unplug the vacuum first.
2. Belt issues: The brushroll is usually powered by a belt. Over time, the belt can become worn, loose, or stretched, leading to a lack of brush spin. Inspect the belt for any signs of damage or wear. If needed, refer to the user manual or contact Shark customer support to replace the belt.
3. Motor or power issues: If the brushroll is not spinning and there are no visible obstructions or belt problems, it could indicate a problem with the motor or power supply. Check if the vacuum is securely plugged into a working outlet. If the power seems to be functioning correctly, and the brushes still don't spin, there may be an issue with the motor itself. In this case, it is recommended to contact Shark customer support for further assistance or to inquire about warranty coverage.
Remember, always follow the safety guidelines provided by the manufacturer, and consult your user manual or contact customer support for specific instructions related to your Shark NV352 vacuum cleaner model.

There could be several reasons why your Shark NV352 vacuum has lost suction. Here are some possible causes:
1. Clogged filters: Over time, the filters in your vacuum can become clogged with dust, dirt, and debris, causing a loss of suction. Make sure to clean or replace the filters regularly according to the manufacturer's recommendations.
2. Full dustbin or dirt cup: If the dustbin or dirt cup is full, it can restrict airflow and reduce suction. Empty the bin and ensure it is properly placed back in the vacuum.
3. Clogged hose or attachments: Check the hose and attachments for any blockages. Detach them from the vacuum and inspect for any clogs or obstructions. Clear any debris that may be obstructing the hose or attachments.
4. Worn brush roll or belt: If the brush roll or drive belt is worn out, it may not spin properly, reducing suction. Examine the brush roll and belt for any signs of damage or wear. Replace them if necessary.
5. Clogged brush roll: Hair, string, or other debris may get tangled in the brush roll, affecting its performance. Remove the brush roll and clean it thoroughly, ensuring there are no obstructions.
6. The vacuum is overheating: If the vacuum has been running for an extended period, it may overheat and lose suction. Allow it to cool down completely before using it again.
7. Motor issues: In some cases, a malfunctioning motor can lead to a loss of suction. If you've checked all the above points and the vacuum still doesn't have proper suction, it could be a motor problem. In such cases, contacting Shark customer support for assistance or taking it to an authorized service center might be necessary.
Remember to always consult the user manual or contact Shark customer support for specific troubleshooting steps related to your model.
