Dyson Hoover Brush Bars: What They Do and How to Keep Them Working

Dyson vacuum brush bars are a key part of your hoover’s cleaning power—especially on carpets. Sometimes called agitators or beater bars, they sit inside the main cleaner head or tools like the Mini Motorhead and Hair Screw Tool.

If you’ve noticed your Dyson struggling with hair or dirt on carpets, the brush bar is one of the first parts to check.

What Does a Dyson Brush Bar Do?

The brush bar spins at high speeds—up to 3,500rpm in some models—using its own motor to lift dust, dirt, and hair from deep in carpet fibres. This spinning action boosts cleaning performance, especially in homes with pets or long hair.

Some Dyson brush bars, like those in the Hair Screw Tool, have a conical, anti-tangle design. This helps prevent hair from wrapping around the bar—saving you time and keeping your vacuum working efficiently.

Common Dyson Brush Bar Problems (and How to Fix Them)

Brush bar not spinning? Here’s what could be wrong:

• Hair or threads tangled around the bar

  • Fix: Remove the cleaner head and cut away any debris with scissors.

• Blocked cleaner head, wand or inlet

  • Fix: Check and clear any clogs in the airways to restore performance.

• Worn or bent brush bar

  • Fix: If it looks damaged, it’s time for a replacement to avoid further issues.

• Motor or drive belt fault

  • Fix: If the brush is clean but still won’t spin, the issue might be internal—consider professional repair or replacing the full cleaner head.

Maintenance Tip: Clean the brush bar every few weeks—especially if you have pets. This helps avoid tangles and keeps suction strong.

Types of Dyson Brush Bars

  Found in most floorheads, ideal for carpets and rugs.

Why Replacing a Worn Brush Bar Matters

If your Dyson isn’t cleaning as well as it used to, the brush bar could be the reason. Over time, bristles flatten, parts wear out, and hair builds up. Replacing a faulty bar can:

• Restore deep-cleaning power on carpets

• Reduce noise and vibration

• Protect the motor and cleaner head from damage

Keep Your Dyson Cleaning Like New

With regular maintenance and the right replacement parts, your Dyson hoover can stay powerful for years. If your brush bar is showing signs of wear or no longer spinning properly, it’s time to swap it out.

Use genuine Dyson brush bars to ensure the best fit and performance for your model.
