The Sanitaire 53272 is the OEM 12-inch VibraGroomer I (VGI) brushroll for SC600 and SC800 Series uprights. The VGI design pairs two bristle strips with two beater bars to agitate carpet fibers and loosen embedded dirt.

When bristles wear flat or beater bars crack, carpet agitation drops sharply; replacing the brushroll restores full pickup performance. Fits Sanitaire SC600 and SC800 Series uprights. Genuine Sanitaire part 53272.
