Preliminary Checks
Before diving into more complex troubleshooting, perform these basic checks:
- Power: Ensure the vacuum is properly plugged in and the power switch is turned on.
- Bin Empty: Check if the dustbin is full. An overfilled bin can sometimes interfere with the vacuum’s operation.
- Cord Condition: Inspect the power cord for any visible damage or frayed wires.
Step 1: Check for Blockages
The most common reason for a brush roll to stop spinning is a blockage. Hair, string, and debris can easily get tangled around the brush roll, preventing it from rotating freely.
- Unplug the Vacuum: Always unplug the vacuum cleaner from the power outlet before performing any maintenance or troubleshooting.
- Locate the Brush Roll Access: On the Shark UV850, the brush roll is typically accessed by releasing the brush roll cover plate on the vacuum head.
- Remove the Brush Roll: Carefully remove the brush roll from the vacuum head.
- Inspect and Remove Debris: Thoroughly examine the brush roll for any tangled hair, string, or debris. Use scissors or a seam ripper to carefully cut and remove the tangled materials.
- Clean the Brush Roll Housing: Check the brush roll housing for any accumulated dirt or debris. Remove any obstructions that could hinder the brush roll’s movement.
- Reinstall the Brush Roll: Once the brush roll and housing are clean, reinstall the brush roll into the vacuum head and secure the cover plate.
Step 2: Reset the Brush Roll
The Shark UV850 may have a reset function for the brush roll, especially if it has a sensor that detects obstructions.
- Locate the Reset Button: Check the vacuum cleaner’s manual or the Shark website for the location of the brush roll reset button. It’s often a small button located near the brush roll housing.
- Press and Hold: With the vacuum unplugged, press and hold the reset button for 10-15 seconds.
- Test the Brush Roll: Plug the vacuum back in and turn it on to see if the brush roll is now spinning.

Step 3: Check the Brush Roll Motor
If the brush roll still isn’t spinning after clearing blockages and resetting, the issue might be with the brush roll motor.
- Listen for Motor Sound: Turn on the vacuum and listen closely to the brush roll area. If you hear a humming or grinding sound, the motor might be trying to turn but is unable to do so.
- Inspect the Motor: (This step requires some technical skill) Disassemble the brush roll housing to expose the motor. Visually inspect the motor for any damage or loose connections.
- Test the Motor with a Multimeter: (This step requires some technical skill and safety precautions) Use a multimeter to test the motor’s continuity. If there’s no continuity, the motor may be faulty and need replacement. Note: If you’re uncomfortable performing this step, consult a qualified appliance repair technician.

Step 4: Inspect the Belt (If Applicable)
Some Shark UV850 models use a belt to drive the brush roll. If the belt is broken or stretched, the brush roll won’t spin.
- Locate the Belt: Access the brush roll housing and locate the belt that connects the motor to the brush roll.
- Inspect the Belt: Check the belt for any signs of damage, such as cracks, tears, or stretching.
- Replace the Belt: If the belt is damaged, replace it with a new belt that is specifically designed for the Shark UV850 model.

Step 5: Check the Sensors
Some Shark vacuums have sensors that detect when the brush roll is encountering resistance. If these sensors are malfunctioning, they may prevent the brush roll from spinning.
- Locate the Sensors: Consult your vacuum’s manual to locate the brush roll sensors. They are usually near the brush roll housing.
- Clean the Sensors: Gently clean the sensors with a soft, dry cloth to remove any dirt or debris that may be interfering with their function.
- Test the Sensors: Turn on the vacuum and observe the sensors. If they appear to be malfunctioning, they may need to be replaced.
