Replacing the Dyson DC25 Drive Belt — Step by Step
Replacing the Dyson DC25 drive belt is a DIY job of about 10 minutes. 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.

⚠ 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.

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.
