Know before you buy
No, this specific part (159394) is engineered exclusively for the Generation 3 and Generation 4 upright models. It will not fit other Kirby generations or series.
You should consider a replacement if the bristles on your current brush roll are visibly worn down, matted, or missing. If you notice your vacuum is no longer effectively agitating your carpet or picking up debris as it once did, the brush roll is likely the culprit.
This listing is for the brush roll unit only. It does not include additional hardware like end caps or bearings, so you should retain your existing components during installation.
Yes, this is a genuine replacement part identified by Kirby part number 159394, ensuring it meets the original manufacturer's specifications for your G3 or G4 vacuum.
While this brush roll is designed primarily for deep cleaning carpets, it is safe to use on hard floors. However, its main function is to agitate carpet fibers to lift embedded dirt, so you may find it most effective on rugs and wall-to-wall carpeting.
