About the Dyson DC33

The Dyson DC33 corded upright has a powered cleaner head with a bristle brush bar driven by a belt. Worn bristles and wound hair are what most owners are replacing — a straightforward job on this older model.

Step-by-Step: Replacing the Dyson DC33 Brush Roll

1
Unplug the vacuum
Disconnect the DC33 before opening the cleaner head.
2
Remove the soleplate
Lay the head flat and release the soleplate to reach the brush bar.
3
Lift out the old bar
Ease the bar out and cut away wound hair from it and the housing.
4
Check the belt
Confirm the drive belt is intact and seated; replace it if stretched or broken.
5
Fit the new bar and test
Seat the new bar, refit the soleplate, plug in and confirm it spins.

⚠ Common mistakes on the DC33

The DC33 mistake is swapping the bar when a stretched/broken belt or wound hair is the real cause. The second is not clearing the housing channel, so the new bar runs off-balance and wears fast.

✓ OEM vs aftermarket for the DC33

A genuine Dyson bar guarantees the right bristles and fit; aftermarket bars are cheaper and fine when the listing names the DC33. Inspect and replace the belt while the head is open if it's worn.

🔁 How often to replace

The Dyson DC33 brush roll should be replaced Every 12-24 months under normal use — sooner with pets or daily heavy use. Signs it's due: Poor carpet pick-up, visible wear.
