Carpet that still looks flat after a full pass is almost always a brush problem, not a suction problem. This is the genuine Kirby brush roll for G5, G6, Ultimate G, Diamond Edition and Sentria uprights - a wooden roller with sealed ball bearing ends, black nylon bristles and the magnet mounted on the large end cap, where these machines expect it. It is the part owners reach for when the bristles have worn short, the roller rattles, or the belt keeps walking off, and it is a standard shelf item for shops that service Kirby machines.
Built for
- Kirby uprights that no longer lift pile or leave visible grooming marks
- Brush rolls with worn, splayed or missing bristles after years of use
- Roller ends that rattle, drag or squeal because the bearings are shot
- Full refurbishments where the belt, brush roll and bearings are done together
Why the brush roll wears before anything else
Suction lifts loose debris off the surface; the brush roll is what pulls embedded grit up out of the pile so the airflow can take it. Bristles shorten steadily with use, and once they no longer reach into the carpet the machine feels weak even though the motor is perfectly healthy. The bearings are the second half of the story - a roller that has developed drag steals power from the belt, runs the belt hot, and shortens the life of every part downstream of it.
Two details matter when ordering a Kirby brush roll. The magnet has to be on the correct end, because it is what the machine reads, and the end cap size has to match. This roller carries the magnet on the large end cap, which is the configuration used across the G5 and later generation machines listed below.

Frequently asked questions
Which Kirby models does this brush roll fit?
It fits Kirby G5, G6, Ultimate G, Diamond Edition and Sentria uprights. If you are working on an earlier G3 or G4 machine, that generation uses a different roller, so send us the model number first.
How do I know the brush roll needs replacing?
Set a straight edge across the bristles. If they no longer stand proud of the roller by a consistent amount, or if whole rows are splayed and shiny at the tips, the roller is worn. Spin it by hand as well - any grinding, drag or side play means the bearings are finished.
Does this brush roll include the belt?
No, the belt is a separate item. Most shops replace the belt at the same time as the roller, since a fresh belt on a worn roller tends to fail early.
Which end does the magnet go on?
The magnet sits on the large end cap on this roller. Match it to the orientation of the old roller when you install it so the machine reads it correctly.
Are the bristles stiff or soft?
These are standard black nylon bristles, the general-purpose stiffness Kirby uses for mixed carpet. Softer-bristle versions exist for delicate or low-pile flooring if that is what you need.
