Quick answer

Replacing the Dyson DC25 drive belt is a DIY job of about 10 minutes. Compatible drive belts currently start at $6.99 (genuine Dyson OEM from $7.94). Replace it Every 12 months under normal use. Full step-by-step below.

On the DC25 the brush bar is driven by a toothed belt (Dyson part 914006-01) working with the clutch assembly. Because the belt is geared it seldom stretches; a bar that won't spin is usually a snapped belt or, less often, a worn clutch — check the belt first as it's the cheaper fix.

About the Dyson DC25

The Dyson DC25 (2009) is a corded Ball upright with a clutch-driven brush bar. Its brush bar is turned by a geared drive belt in the cleaner head, and the DC25 also has a clutch mechanism that lets you switch the brush bar off for bare floors — both are relevant when the bar stops spinning.

Step-by-Step: Replacing the Dyson DC25 Drive Belt

1
Unplug and set brush control to carpet
Disconnect the DC25 and confirm the cleaner-head control is set to carpet, not bare floor, so you're not chasing a clutch setting.
2
Open the soleplate
Lay the head flat and release the soleplate on the underside to reach the brush bar and belt.
3
Lift the brush bar
Ease the brush bar out to expose the geared belt around the drive gear.
4
Swap the belt
Slide the old belt off, clear tangled hair from the channel, then loop the new 914006-01 belt onto the drive gear and brush-bar hub.
5
Reassemble and test
Refit the bar and soleplate, plug in, set to carpet and confirm the bar spins.

⚠ Common mistakes on the DC25

Owners often replace the belt when the real issue is the clutch switched to bare-floor mode — confirm the brush control is set to carpet first. The other mistake is fitting a plain rubber belt; the DC25 uses the geared 914006-01 belt only.

✓ OEM vs aftermarket for the DC25

The genuine Dyson 914006-01 belt is inexpensive and exact; aftermarket equivalents are widely sold — just make sure the listing shows the toothed geared belt for the DC25, not a generic upright loop.
