Eureka Upright Power Cord -...

Product details
Part 5237017 is a 30-foot, three-wire replacement power cord for the Sanitaire SC679J commercial upright and the related SC689A, SL635A, and SL635B models. That extra length is the whole point of a commercial cord: it covers a corridor, a classroom, or a large retail floor without stopping every few steps to find another outlet.
Commercial cords tend to fail in two spots: at the plug end, from being yanked out by the cord rather than the connector itself, and at the handle end, from the constant flex of every pass across a floor. Watch for nicked or split insulation, a section that has gone flat, or power that drops out the moment the cord shifts underfoot. Wrapping a damaged spot in tape is not a fix, and any cord with compromised insulation belongs off the machine entirely.
- Part: 5237017, 30 ft, 3-wire commercial cord
- Fits: Eureka and Sanitaire SC679J, SC689A, SL635A, SL635B
- Function: Supplies power with extended reach for commercial routes

Disconnect the machine fully before starting the swap, and route the new cord the way the original ran so it keeps the same protection where it enters the handle.
A cord like this one is worth replacing at the first sign of trouble instead of patching it, since a machine on a daily commercial route racks up more flex cycles on its cord in a single month than a household vacuum sees across years of occasional use. Keeping a spare on the shelf means a damaged cord takes a machine out of service for minutes rather than the better part of a day.
