Product details
Part 4948416 is the full base assembly for a Sanitaire 679, 684 or 688 commercial upright, the molded housing carrying the brush roll, drive belt, and nozzle-mounting points as one piece. It is built for the inside-wheel setup; a separate item exists for machines running outside wheels, so confirming which layout is fitted before ordering saves a return trip through customer service.
A base usually gets swapped only once the plastic itself has given out, not because of any single part inside it. Cracks near the brush roll mounts, snapped mounting tabs, or a nozzle edge worn down enough to tilt how the housing rides over the pile all point to the same complaint from the floor: cleaning that comes out uneven across the nozzle's width, alongside a drive belt that wears through again and again no matter how many replacements go on it.
Since this housing carries every other moving piece in the nozzle assembly, a cracked one is worth swapping outright rather than patched, as a repaired crack rarely survives the flex of daily commercial use. Getting the wheel style right matters here specifically, since the inside-wheel and outside-wheel bases are catalogued as separate assemblies rather than interchangeable versions of one part.
- Part: 4948416 base assembly, inside-wheel version
- Function: houses and mounts the brush roll, drive belt, and nozzle
- Fits: Sanitaire 679, 684 and 688, and Eureka and Sanitaire C2094B and SC679J
Move the existing brush roll and drive belt over from the old base once the new one is installed; neither part ships included with the assembly.
