Well, the provided links are about as helpful as a screen door on a submarine for this particular question, so let's rely on some good old-fashioned cleaning know-how.
Ah, the age-old question: Can my mighty, carpet-conquering Shark also rescue my sofa from that mysterious stain that looks suspiciously like last Tuesday's pizza? The short answer is a resounding "Probably!" Most Shark carpet cleaners come equipped with a hose and an upholstery tool specifically for this noble mission. They wouldn't give you that little gadget just to have it languish in a closet.
However, before you go full-on cleaning commando, you must consult the sofa's oracle: the care tag. This little fabric square holds the key to your success or a sudsy, tragic failure. Look for a letter code. If you see a "W" or "W/S," congratulations! This means your sofa is cleared for a water-based cleaning assault. If you see an "S," back away slowly; that means solvent-based cleaners only, and your Shark's water-based solution will cause chaos. And if you see an "X," do not pass go, do not collect $200. This means vacuum only, and water is its mortal enemy.
Even with a "W" clearance, always perform a spot test in a hidden area, like the back or under a cushion. Apply a little cleaner, let it dry, and make sure your sofa doesn't react with bizarre colors or textures. If all looks good, you're clear to unleash the Shark and reclaim your couch from the clutches of grime.
