The end cap is the round retainer at the end of the brush bar in a Dyson DC24 cleaner head. It does two jobs: it holds the roller square in its housing while the machine runs, and it is the part you remove to take the roller out and cut hair off it. Because it is handled every time the head is serviced, it is one of the first pieces on a DC24 to crack or wear loose.
Built for
- DC24 owners whose cleaner head has started to rattle, knock or buzz on hard floors
- Households with pets, where the cap gets opened often to cut hair off the roller
- Anyone who snapped the original cap while forcing it during a clean-out
- Refurbishers bringing a secondhand DC24 back to quiet running
Use cases
Noise is the usual giveaway. A cap that has worn oval, or that is no longer clipping down fully, lets the brush bar float a fraction in its bearing seat, and that shows up as a knock or buzz that follows the roller speed. The other common case is simple breakage: the cap is removed under load with a screwdriver, a tab snaps, and from then on the roller will not stay captive. Neither fault stops the vacuum outright, which is why it often gets ignored until the roller starts chewing the housing.

Fits
Distributors list this cap for the Dyson DC24 upright family, which sellers describe as including the DC24 Animal, DC24 Multi Floor and DC24i trims. Dyson used different cleaner head hardware across model generations, so a DC24 cap should not be ordered for a DC25, DC33 or Ball-series machine. Check the model number on your machine's label before ordering.
Frequently asked questions
What does the end cap actually do?
It retains the brush bar in the cleaner head so the roller spins square in its seat, and it is the removable access point for taking the roller out to clear hair and thread.
My DC24 cleaner head has started rattling. Is this the part?
It is the first thing to check. A cap that has worn oval or lost a retaining tab lets the brush bar move in its seat, which reads as a knock or buzz that rises and falls with roller speed.
Does the brush bar come with it?
No. This is the end cap only. The brush bar, or brush roll, is a separate part and is ordered separately if the bristles are also worn.
Do I need tools to fit it?
In most cases no. The cap is designed to be released and refitted by hand for routine roller cleaning. Forcing it with a screwdriver is what breaks the original in the first place.
Will a DC25 or DC33 end cap fit my DC24?
Do not assume so. Dyson changed cleaner head hardware between model generations. Order the cap listed for your machine's model number.
