For a couch with a visible stain, the HydroSteam 3618 does the full job. Its Steam mode is the one the maker points to for refreshing upholstery, SteamWash handles tougher oily marks, and the plain Wash mode keeps a cold option for fabrics that dislike heat. Crucially, it extracts, so the loosened soil and the water leave the cushion.
It is a small portable, which means the tank runs out on a full sectional and you will refill several times. The price tier sits higher than the generic steamers, which is what you pay for a known maker and its parts. Compared with the 3 second steamer, it is slower to set up but far more capable on stains.
Start with the Wash mode on any cushion you have not cleaned before, and move to steam only on fabrics that tolerate it. Never park the nozzle on one patch, and blot between passes with a dry towel. Prop cushions on edge afterward so air can reach the foam core. A sectional is easiest if you treat one cushion at a time and carry it outdoors or to a well ventilated room, because a damp cushion in a closed living room can stay damp overnight. If your sofa has removable covers, check the tag before you wash them separately, since a cover that can be machine washed is simpler than any steam job.
