About the Dyson DC50
The Dyson DC50 is a compact corded Ball upright with a powered cleaner head. Its brush bar is a bristle roller driven by a toothed geared belt — the bar that flattens and tangles with hair over time.
The DC50 brush bar sits behind the soleplate and is turned by the DC50-specific geared belt. Replace the bar when the bristles are worn flat or it's cracked; if it won't spin at all with the belt intact, check the belt and brush control first.
