This is a genuine Eureka OEM brush roll, part number 16156-1 (also listed as E-16156-1), for the Eureka AirSpeed Zuum line of bagless upright vacuums. It fits the AS5203A, AS5204, AS5204A, and AS5204A-1 models.

As a wear item, the brush roll should be replaced when bristles flatten or pickup performance drops. Because this is the genuine Eureka part, fit matches the original equipment.
