Step-by-Step: Replacing the Dyson V12 Detect Slim Brush Roll

1
Power off and flip over
Turn off your Dyson V12 Detect Slim and place it face-down on a soft surface to protect the finish.
2
Remove the brush roll cover
Use a coin or flathead screwdriver to release the cover clips. The cover should lift away cleanly.
3
Slide out the brush roll
The brush roll is held by end caps — pull gently toward you to disengage.
4
Cut away tangled hair/debris
Before installing the new roll, clear any debris from the housing channel.
5
Install the new brush roll
Align the new roll and press the end caps into their slots until they lock.
6
Replace cover and test
Reattach the cover, press until all clips engage, then test on carpet.

⚠ Common mistakes to avoid

  • Confirm the part matches your exact model number before buying — Dyson reuses parts across lines.
  • Never wash a filter unless it's marked washable, and dry it fully (24h) before refitting.
  • Don't force the part — if it resists, check alignment before applying pressure.
  • Always disconnect power (or remove the battery) before any internal work.
