How do you remove the roller from a Dyson?

To remove the brush bar roller from a Dyson vacuum cleaner, you'll typically use a coin to unlock it.

Here's a step-by-step guide:

1. Locate the Release Mechanism: Find the slot or dial on the cleaner head, usually located on the side. This is what locks the brush bar in place.

2. Insert a Coin: Grab a suitable coin (a dime or similar sized coin will often work well). Insert the coin into the slot.

3. Turn the Coin: Twist the coin anticlockwise (counter-clockwise). This will unlock the brush bar. You might hear a click.

4. Remove the Brush Bar/Roller: Once unlocked, the brush bar should be able to be pushed out from its housing. You may need to gently wiggle it.

5. Remove Drive Bar (If applicable): Some models may also have a drive bar that can be removed after the roller is taken out.
