I agree with the others. I have cleaned many “solvent only” couches with no problem using our 101. There are “dry foam shampoos” out there that are available for such furniture, although we have tried them and are not overly impressed with them. Also, they wouldn’t work in your situation with urine. Just a reminder, the codes on the tags (“x”, “s” and “w”) technically only tell you the stability of the dyes used (and subsequently the manufacturer recommends a particular style of cleaning for that code). If you can, go look at the piece and use your judgement from there.
Oh, by the way, NEVER use straight solvent through a manchine not made for it (i.e. u-mate and ninja). They make machines strictly for solvents. Have heard stories in IICRC classes about people trying it (notice I said stories, not techniques, that should tell you what you need to know!).
