Roomba Combo vs vacuum-only parts

j7 and Combo j7+ share a name and not always a battery, mop pad, or bag SKU.

1. Read the nameplate: Combo is printed on mop models.
2. Filters for vacuum-only j usually follow e/i/j.
3. Mop pads only belong on Combo decks.
4. If the parts page lists two batteries, treat the other one as Unverified for your body.
