how do you clean the brush bar on a dyson ball animal 2? it's wrapped with hair.

Diagnosis

Hair and fiber wrap on the Dyson Ball Animal 2 brush bar occurs when long strands of hair, carpet fibers, and pet fur wind around the rotating bristles. Because the brush bar spins at high RPMs, these materials tighten into a dense "sleeve" around the axle. Over time, this creates excessive friction, which puts a mechanical strain on the brush motor and can lead to the drive belt slipping or snapping. You can confirm this is the issue if you notice a significant drop in suction performance or if you hear a high-pitched whining sound coming from the cleaner head during operation. In severe cases, the brush bar may stop spinning entirely, or you may see a "brush bar blocked" indication if your specific sub-model features an electronic sensor. If you see a buildup of greyish lint and hair clumps clinging to the bristles, the bar requires immediate manual extraction to prevent motor burnout.

How to Fix It

1. Power Down: Completely unplug the vacuum from the wall outlet. If you are using a cordless variant of the Animal line, ensure the battery is removed or the power switch is firmly in the 'off' position to prevent accidental activation.
2. Positioning: Lay the vacuum on its back on a flat, hard surface. This exposes the underside of the cleaner head and the red release mechanisms.
3. Release the Head: Locate the red release button on the underside of the ball assembly. Press and hold this button while sliding the cleaner head assembly away from the main body of the vacuum.
4. Unlock the Brush Bar: On the side of the cleaner head, locate the brush bar release cap (usually a plastic end cap). Press the release button and rotate the end cap upwards exactly 90 degrees. This unlocks the axle from the drive gear.
5. Extraction: Grip the brush bar firmly and pull it straight out of the housing. Do not wiggle it side-to-side, as this can bend the drive pins.
6. Debris Removal: Use a pair of heavy-duty scissors or a seam ripper. Cut the hair and thread along the length of the bar. Do not pull the hair forcefully, as this can pull the bristles out of the plastic molding. Ensure you clear the debris from the bearing ends where the bar meets the motor.
7. Reinstallation: Slide the clean brush bar back into the housing. Ensure the bar is pushed firmly all the way in until it clicks. Rotate the end cap back down to its original horizontal position and snap it into place.

If That Didn't Work

• Check the Drive Belt: If the bar is clean but still won't spin, inspect the rubber drive belt. Look for frays or a complete snap. If the belt has stretched or snapped, the brush bar will not rotate regardless of how clean it is. You will need to replace the belt assembly using a compatible Dyson Animal 2 replacement kit.
• Inspect the Motorhead Gears: Remove the brush bar and look into the gear housing. Check for small pebbles or hard debris (like coins or plastic toy pieces) that may be jamming the gear teeth. Use a flashlight and a can of compressed air to clear any hidden obstructions.
• Test the Power Switch: Ensure the brush bar toggle switch (located on the handle or body) is actually engaging. If the switch feels "mushy" or doesn't click, the internal wiring may have frayed, preventing power from reaching the brush motor.
• Clear the Air Path: Sometimes a "blocked" feeling is actually a clog in the neck of the cleaner head rather than the brush bar. Disconnect the hose and drop a coin or a small ball through the neck; if it doesn't fall through to the brush bar area, there is a clog in the intake throat.

Heads Up

• Avoid Water: Never rinse the brush bar or the cleaner head housing under a tap. Water trapped in the motor housing can cause a short circuit or lead to rust on the axle pins. Use a dry cloth or a vacuum to clean the housing.
• Bowel Maintenance: To prevent future buildup, perform a "quick trim" of the brush bar every two weeks using scissors without fully removing the bar, if possible.
• Bristle Care: If you notice the bristles are worn down or missing, replace the entire brush bar. Worn bristles fail to agitate the carpet, which forces you to pass over the same area multiple times, increasing wear on the motor.
• Clear the Soleplate: While the bar is out, wipe the underside of the cleaner head (the soleplate) with a damp cloth to remove sticky residue that can cause the head to "drag" on hardwood floors.
