Electrolux-Eureka Sanitaire Brush Roll Belt - SC5500 / S5000 Eon

The brush roll belt for the Sanitaire SC5500, S5000 and Eon commercial uprights is stocked here as part A03838001, catalogued under that name for the roller it turns.

It fits the Electrolux-Eureka S5000, the Eureka S5000A, SC5500A, SC5500B and SC5505A, and the same numbers badged Sanitaire: S5000A, SC5500A, SC5500B and SC5505A.

A belt that has stretched or glazed over stops gripping, so the roller turns slowly or stalls under carpet load while the motor keeps running at full speed. Look for a shiny hardened face, cracks across the ribs, a loop that no longer springs back when it is stretched between two fingers, and the smell of hot rubber after a few minutes of use. None of those need the belt to have snapped before they are worth acting on.

On a machine that runs every day, this is worth checking on a set schedule rather than at the point it breaks, since the work to reach it is the same whether it is replaced early or after it fails. Clear wound hair and thread off the roller while the machine is open, because a roller that is hard to turn by hand is what loads a belt hardest in the first place.
