Kirby Soft Helix Brush Roll...

Product details
The Kirby Avalir II accepts a soft helix brush roll, sold as part 152517, where bristle rows spiral around the tube instead of sitting in straight lines, letting the roll contact the floor a little at a time rather than all at once.
That gentler bristle set is built for hard floors and finer carpets, surfaces where the machine's standard, stiffer roll would put down more force than the material can take. Wear on this style creeps in quietly: bristles thin and splay row by row, usually starting wherever the helix does the most work, and cleaning drops off gradually enough that many owners suspect the bag before they think to check the roll.
Rotation that has gone uneven, scuffing concentrated at one end, or bare patches tracing the helix pattern all point to a roll that is finished. Clear hair and thread from the shaft ends whenever the belt gets changed, since debris packed against the bearing caps is the single most common reason these rolls get retired before their bristles are actually spent.
Spin the new roll by hand before closing the base and confirm it turns freely with no drag on either end, since a bearing seated even slightly off will bind once belt tension is applied.
