An improved vacuum cleaner brushroll including a tufted spindle supported by end assemblies. The end assemblies have bearings that rotatably mount the spindle in a vacuum cleaner nozzle. Rotation of the spindle is effective to pick up debris. The improvement comprises the spindle being a hollow tubular member. Each of the end assemblies includes a plug fitted into a respective axial end of the spindle. The plug or spindle has ribs in a cylindrical surface which engage the material of the other of the plug or spindle to resist rotation between the spindle and the plug. One of the bearings has a first portion operably connectable with the plug. A relatively rotatable second portion of the bearing is operably connectable with a brushroll mounting structure of the vacuum cleaner nozzle.
