how do you clean the fluffy roller head on a dyson v8? it's got hair wrapped all around it.

You need to remove the brush bar to clean it. First, make sure your machine is disconnected from the charger.

1. Press the cleaner head release button on the end of the wand and place the cleaner head upside down.
2. Locate the end cap on the side of the cleaner head. Push it up fully and pull the brush bar out.
3. Remove the end cap from the brush bar. Do not wash the end cap.
4. Hold the brush bar under running water and gently rub to remove lint and hair. Run your hand down its length to squeeze out water.
5. Stand the brush bar upright with the closed end at the top. Let it dry completely for at least 24 hours.
6. Once dry, reattach the end cap. Slide the brush bar back into the cleaner head and push the end cap down to the closed position.

If that didn't work: If the roller still won't spin, check for blockages inside the cleaner head's air inlet. Also, ensure the brush bar is completely dry before reassembly; a damp part can cause issues.

Heads up: Never put the cleaner head in a dishwasher or use detergents, polishes, or air fresheners. It contains electronic components.
