Remove the brush roll by unclipping the end caps and sliding the brush out

Most Shark vacuums have a brush roll (also called a beater bar) that sits across the bottom of the cleaning head. To remove it, first unplug the vacuum from the wall. Flip the vacuum over so you can see the underside of the cleaning head.

Look for two plastic end caps on either side of the brush roll — these usually sit at the corners where the brush meets the housing. Push or pull these caps outward (the direction varies by model, so check which way yours moves). Once both caps are released, the brush roll will slide straight out toward you. Set it on a clean surface so you can inspect it for hair, string, or debris.

Key Takeaways

  • Unplug the vacuum and flip it over to access the brush roll from underneath the cleaning head.
  • Release the end caps on both sides of the brush by pushing or pulling them outward, then slide the brush straight out.
  • Remove wrapped hair and lint by hand, then rinse the brush under warm water and let it dry completely before reinstalling.
  • Reinstall the brush by sliding it back into the housing until both end caps click into place.
  • Clean the brush every one to two months, or sooner if you have pets or long hair in your household.

Clear hair and debris from the brush by hand first

Hair and string wrap tightly around the brush roll during normal use. Before rinsing, pull away as much of this debris as you can with your fingers or a small comb. Work along the entire length of the brush, turning it as you go so you catch wrapped material on all sides.

If hair is stubborn or matted, use a seam ripper, old toothbrush, or the edge of a plastic comb to gently loosen it. Do not use a sharp knife or metal tool — these can damage the bristles. Once you have removed the bulk of the hair, the brush is ready to rinse.

Rinse the brush under warm water and air-dry it completely

Hold the brush roll under warm running water and rotate it slowly so water flows over all the bristles. You can use your fingers or a soft brush to work away any remaining lint or dust. Do not soak the brush or use hot water, as this can damage the bristles or the plastic end pieces.

After rinsing, shake off excess water and stand the brush upright on a clean towel or paper towel. Let it air-dry for at least two to four hours before you put it back in the vacuum. If the brush is still damp when you reinstall it, moisture can damage the motor or create mold inside the vacuum head.

Reinstall the brush by sliding it back into the housing

Once the brush is completely dry, flip the vacuum over again and position the brush roll so the ends line up with the slots in the housing. Slide the brush straight in until you feel it seat fully. The end caps should click or snap back into place on both sides — you will hear or feel a small snap when they lock.

Push down gently on the brush to make sure it does not move or rattle. If it shifts, the end caps may not be fully seated. Remove the brush and try again, making sure the ends are aligned with the slots before sliding it in.

Know when the brush roll needs replacement instead of cleaning

If the bristles are matted, bent, or missing in patches, or if the brush still smells bad after rinsing and drying, the roll has reached the end of its life. Shark brush rolls typically last one to two years with regular cleaning, depending on how much you vacuum and whether you have pets.

To order a replacement, find your vacuum model number (usually on a sticker on the back or bottom of the unit) and search for "Shark [model number] brush roll" online. Replacement rolls cost between $20 and $50 and take five minutes to install using the same steps you used to remove the old one.

Clean the brush roll every one to two months for best performance

A clogged brush roll loses suction and leaves dirt behind on your floors. If you have pets or long hair, clean the brush once a month. If you live alone and vacuum less often, every two months is usually enough. A quick visual check — flip the vacuum over and look at the brush — takes ten seconds and tells you whether it needs cleaning.

Regular cleaning also extends the life of the brush and keeps the motor from working harder than it needs to. A motor that runs cool lasts longer than one that overheats because it is fighting a clogged brush.

Frequently Asked Questions

Can I wash the brush roll in the dishwasher?

No. The heat and water pressure in a dishwasher can damage the bristles and loosen the glue that holds them to the core. Hand-rinse under warm water only, and let it air-dry before reinstalling.

What if the end caps won't come off?

Do not force them — you may crack the plastic. Check your vacuum's manual to confirm which direction they release (some push in, some pull out). If they still will not budge, try gently wiggling the cap side to side as you explore pressure. If the cap is cracked or broken, you will need to order a replacement end cap kit for your model.

How do I know if the brush roll is installed correctly?

The brush should sit flat and centered in the cleaning head with no gaps on either side. When you spin it by hand, it should rotate freely without rubbing or catching. If it wobbles or does not spin smoothly, remove it and reinstall it, making sure both end caps are fully seated.

Can I use the vacuum while the brush is drying?

No. Running the vacuum without the brush roll can damage the motor and the cleaning head. Always wait until the brush is completely dry before reinstalling it. If you need to vacuum right away, order a replacement brush roll so you have a spare while one is drying.

Why does my brush roll smell bad even after cleaning?

Mold or mildew is growing inside the bristles. Soak the brush in a solution of one part white vinegar to three parts water for 30 minutes, then rinse thoroughly under warm water and air-dry completely. If the smell returns after a few uses, the brush has reached the end of its life and should be replaced.
