The Self Cleaning Brush roll technology actively removes hair from the brush roll while the vacuum is running. If you see hair wrapped around the brush roll please perform the following steps:
If available take the vacuum to a hard floor (Tile, Hardwood floor). Place the carpet setting to "Carpet Low Pile" setting. Run for 30 second interval. Then shut off and unplug the vacuum. Inspect the nozzle for hair on the brush roll.
If there is still hair wrap repeat the above 3 more times until the hair is cleared.
If there are still hair wrap issues, please ensure the vacuum is shut of and unplugged. Remove the bottom or top plate (depending on your model) that gives access to the brush roll. Clean the brush roll of any hair, dirt and debris. Replace the nozzle cover, ensuring it is secured in place per the instruction manual.
