This is the flat drive belt for Dyson DC07 uprights built without the clutch system. On a non-clutch DC07 a single belt runs from the motor spindle straight to the brush bar, so the brush turns whenever the machine is on. That direct arrangement is simple and reliable, and it also means the belt is the part that gives out first. A stretched belt is easy to miss because the vacuum still sounds completely normal. What changes is the pickup on carpet, because the brush bar is no longer being driven hard enough to agitate the pile and lift embedded grit. A belt that has snapped outright is obvious. A belt that has simply stretched over a couple of years is the one that quietly makes people think their vacuum has worn out.
Built for
Carpet pickup that has fallen off
If the machine picks up fine on hard floors but leaves grit in carpet, the brush bar is the suspect and the belt is the first thing to check. It is the cheapest part in the drive path and the one that wears.
Routine preventive replacement
Flat belts are commonly changed every four to six months on a machine in regular use, because they stretch gradually rather than failing on a particular day.
Brush bar that will not spin
A brush bar that stops turning while the motor still runs is the classic snapped-belt symptom. Clear any hair wrapped around the brush at the same time, since that load is often what finished the old belt off.
Keeping a long-serving DC07 in use
The DC07 is old enough now that most in service are on their second or third owner. Belts, filters and a brush bar clean-out are what keep one working rather than being replaced.

Frequently asked questions
How do I know if my DC07 has the clutch system?
Clutch models have a clutch assembly between the motor and the brush bar and use a different belt, usually a toothed type. Non-clutch machines drive the brush bar directly with a flat belt and the brush turns whenever the vacuum is on. If your brush bar has a separate on and off control tied to the floor-type switch, you likely have a clutch model and need the other belt.
How is the belt changed?
Unplug the machine and lay it on its top so the brush bar faces you. Turn the three soleplate fasteners a quarter turn with a coin and lift the soleplate away. Pry the old belt off the brush bar, then fit the new belt onto the motor spindle first, seat one end of the brush bar in its slot, and stretch the belt over the brush bar as you rotate it into place. Spin the brush a few turns to confirm the belt is running true before refitting the soleplate.
How often should the belt be replaced?
Around every four to six months is the common recommendation for a flat belt in regular use. Belts stretch continuously rather than failing suddenly, so pickup degrades gradually and is easy to overlook.
The brush spins but carpet pickup is still poor. What else should I check?
Clear hair and thread from the brush bar and its end caps, check the bristles for wear, and check the filters and the cyclone for blockages. A stretched belt and a clogged filter produce similar symptoms, so it is worth ruling out both.
