This is the purchase you make when the bottom of the machine is finished. The base is the part that takes the abuse on a commercial upright: it gets dropped, it wears through at the nozzle lip, and in gritty buildings it abrades from the inside out. This is the complete 12 inch lower base and nozzle assembly for Sanitaire uprights, in the non-Quick-Kleen configuration with the latch-type bag coupling.
The buyers are repair shops and fleet maintenance staff rather than casual owners, because the diagnosis takes some experience. The tell is not usually a visible crack. It is a machine that keeps eating belts, or a brushroll that will not hold alignment because the bearing seats and end-cap recesses have worn out of round. Fit a new brushroll into a worn base and it will track crooked and shred belts exactly like the last one did. Replacing the assembly restores nozzle height, brush alignment and belt path together, which is why piecemeal parts so often disappoint on these machines.
Fleet operators consistently report base and fan-chamber wear, not motor failure, as the dominant reason these uprights leave service, which means the expensive parts are usually fine. Forum members describe the standard repair path as re-brushing and replacing bearings, moving to a full base only once the housing is past saving.
Two fitment details decide whether this is your part. It is the 12 inch path version, and it is the non-Quick-Kleen design, meaning there is no quick-release bottom plate for brush access. It uses the latch-type bag coupling. Listed fitment covers the SC675 and the SC679G, SC679H and SC679J. Cross-series swaps within the Sanitaire line commonly fail on the bag coupling, so match yours before ordering and we will verify it against your model plate.

Frequently asked questions
Does it include the brushroll and belt?
Configurations vary between suppliers, so confirm with us before ordering if you are counting on a brushroll being included. The matching 12 inch brushroll is the VibraGroom / VG-II style, reference 53270A, and it is inexpensive enough that fitting a fresh one with a new base is good practice anyway.
Which models does it fit?
It is listed for the Sanitaire SC675 and the SC679G, SC679H and SC679J. Suffixes matter in this line, and other 600-series machines may use a different base. Read the model plate and we will confirm it.
Is this Quick Kleen or non-Quick-Kleen, and how do I tell?
This is non-Quick-Kleen. A Quick Kleen base has a quick-release bottom plate that lets you get to the brushroll without removing screws. If your current base needs a screwdriver to open the bottom, you have the non-Quick-Kleen design.
Will my existing bag attach?
It uses the latch-type bag coupling. If your machine has the latch-type coupling your bag will fit. Coupling mismatch is the most common failure in cross-series base swaps, so check this before ordering.
Do I need to set nozzle height after installing it?
Yes. Start with the nozzle all the way up and lower it until the brush just contacts the carpet. Too low loads the brush motor and eats belts, and too high leaves soil in the pile.
