This is the stiff bristle brush roll with magnet for the Kirby G series, the part that actually does the agitating every time the machine goes over carpet. Bristles wear down gradually enough that most owners never notice the day the vacuum stopped lifting pile the way it used to. If the bristles are worn to nubs, if the roll rattles in the nozzle, or if the carpet no longer shows grooming marks behind the machine, the brush roll is the part to replace, not the belt.
The stiff bristle version is the right choice for cut pile and dense commercial carpet, where the extra stiffness is what breaks packed soil free of the fiber base so the airflow can carry it away. The integrated magnet catches loose staples, pins and metal debris before they reach the fan, which on a Kirby is a genuinely expensive thing to protect. Ball bearing ends let the roll spin freely under belt tension rather than dragging, so the motor is not fighting the brush.

Frequently asked questions
How do I know the brush roll needs replacing rather than the belt?
If the roll does not turn at all, suspect the belt first, since a Kirby uses a flat drive belt that stretches and snaps. If the roll turns freely but the carpet no longer looks groomed, the machine leaves lint behind, or the bristles are visibly shorter than they were, the brush roll itself is worn. Many owners replace the belt and the roll together.
Should I choose stiff or soft bristles?
Stiff bristles are the standard choice for cut pile and commercial carpet where soil packs into the fiber base. Softer bristles are gentler on delicate or looped goods and on hard floors. If your machine came with a stiff roll and the carpet in the building has not changed, stay with stiff.
What does the magnet do?
It captures staples, pins, paper clips and similar metal debris on the roll before they can reach the fan. Kirby uses a metal fan that can be damaged by hard debris, so the magnet is a small part doing meaningful protective work, particularly in offices and schools.
How often does a brush roll need replacing?
There is no fixed interval because it depends entirely on hours and on how abrasive the carpet is. Inspect the bristles whenever you change the belt, which is commonly every six to twelve months. When bristle height has dropped noticeably or the ends no longer spin smoothly, it is time.
