BISSELL SpotClean Pet Pro Portable Carpet Cleaner, 2458 $137.80 at Amazon

How does this work on upholstery and couch overall? Thank you.

Shows at 169 for me

or do well with white terry cloth, brush, folex, really warm/hot water even in hand pump sprayer or something , and shop vac. A steamer goes a long way towards this as well as many other things.

To remove stains you need chemical + heat (to increase the effects of the cleaner chems) + pressure and agitation to loosen the stains, and suction to pull it out.

this isn't heated so you'll be putting in hot water And i doubt the pressure or suction is very strong certainly no more than a small hand held shop vac which probably isn't more than 30cfm , bit more convenient for sure depending on cleanup and storage.

signigicantly more psi heat, cfm pumpts, heaters are difference between pro spotters and these units. No idea if it's worth it, i do have commercial units but for the dog when was a puppy and kids...i just grab my steamer, shop vac and folex and brush/cloth. Don't see a need for yet another thing to store.
