hair wrapped around dyson v15 brush bar, how do i get it out?

Diagnosis

Hair wrap occurs on the Dyson V15 Detect when long fibers, pet hair, or synthetic threads bypass the integrated anti-tangle combs and wind tightly around the nylon bristles of the Digital Motorbar cleaner head. While the V15 is designed to "de-tangle" during operation, high-density hair or wet debris can create a tight "sleeve" around the brush bar, which increases friction and puts undue stress on the motor. If left unaddressed, this buildup causes the vacuum to trigger its automatic blockage detection, resulting in the motor pulsing (starting and stopping rapidly) or a "Brush bar obstructed" message appearing on the LCD screen. You can confirm this by looking at the brush bar; if you see a solid ring of hair or a "nest" of debris concentrated at the ends of the roller, the mechanical rotation is being hindered, which can eventually burn out the motor if forced.

How to Fix It

To fully clear the brush bar from the V15 Digital Motorbar cleaner head, follow these precise steps:

1. Power down the machine completely. Ensure the vacuum is disconnected from the charging dock and the main wand is detached to prevent accidental activation of the trigger.
2. Flip the cleaner head over so the brush bar is facing upward. Place it on a flat, stable surface.
3. Locate the side cap (the plastic end piece) on the right side of the cleaner head. Insert a coin or a flat-head screwdriver into the slot of the locking mechanism.
4. Rotate the coin 90 degrees anti-clockwise (counter-clockwise) until the cap clicks into the "unlocked" position.
5. Pull the end cap straight out of the housing. This releases the tension on the brush bar axle.
6. Slide the brush bar horizontally out of the cleaner head. If the bar is stuck due to heavy hair wrap, gently wiggle it side-to-side while pulling.
7. Use a pair of sharp scissors or a seam ripper to cut through the hair. Slide the scissors along the length of the bar, being careful not to cut the nylon bristles themselves.
8. Once the hair is sliced, pull the debris off the bar by hand. Ensure you also clear any hair trapped in the "comb" teeth inside the cleaner head housing.
9. Slide the brush bar back into the housing, ensuring it is seated fully. Replace the end cap and rotate it 90 degrees clockwise until it locks firmly.

If That Didn't Work

• Check the Drive Gear: If the bar is clean but still won't spin, check the small gear assembly where the bar meets the motor. Use a can of compressed air to blow out any micro-debris or dust bunnies that may have migrated into the gear teeth, preventing the drive from engaging.
• Inspect for Warped Bristles: If the brush bar has been exposed to high heat or extreme friction, the nylon bristles may have melted or warped, causing them to snag on the inner housing. If you see "beads" of melted plastic on the bristles, the brush bar (Part #V15-MB-ROLLER) needs to be replaced entirely.
• Clear the Air Path: Sometimes the "obstructed" error is actually caused by a clog in the neck of the cleaner head rather than the brush bar. Remove the cleaner head and look inside the neck for clumps of hair or cardboard; use a long stick or coat hanger to push the blockage out toward the wand.
• Reset the Sensor: If the hair is gone but the LCD still shows a blockage, perform a hard reset. Remove the battery and the filter, wait 60 seconds, and then reassemble. This clears the temporary logic error in the V15's sensor array.

Heads Up

• Avoid Water: Never rinse the brush bar under a tap. The nylon bristles are fine, but the axle ends can trap moisture, leading to corrosion of the drive mechanism. Use a damp cloth for cleaning.
• Frequency: If you have long-haired pets, perform this manual cleaning every 2-4 weeks. Relying solely on the anti-tangle combs can lead to "hidden" buildup at the axle points.
• Tool Choice: Always use scissors for hair removal. Never use a utility knife or box cutter, as these can easily slice through the plastic housing or the motor seals of the cleaner head.
• Check the Seal: When replacing the end cap, ensure it "clicks" fully. A loose cap can cause the brush bar to wobble, which leads to uneven cleaning and faster wear on the motor.
