This SEBO 2-Pc. Brush Roll is designed for their wider Automatic X series and Essential G series uprights. The long piece is the same as the SEBO X/G 1-Pc. Brush Roll while the shorter one is for the other side of the belt pulley. Effectiveness is accomplished by arranging the bristles in a 360 degree convergent format on the brush roll. The steep spiral of the bristles, combined with its high speed, efficiently moves the dirt toward the dirt intake. The long wearing bristles are designed to withstand even hard commercial use.
