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