As you are aware, there's much more to upholstery cleaning than using a rinse tool. Also, is it a case of overwetting or underdrying
IMO it's essential to have a dedicated upholstery tool. They normally have quite small jets (my Prochem Chisel nose with 20+ years use had an 01 jet, and sometimes this felt too much!)
It's important to have the preparation right to minimise the amount of fluid used in the rinse. You can then use everything at your disposal to provide a minimal amount of residual moisture. ie extra dry passes as required, toweling and turbo blower.
Don't make wild untenable claims about drying times. With HWE, if I think a suite is going to be dry in a few hours I will always add that it would be wise to leave it to aire overnight. Feeling dry and being dry are often two different things. Classic example is Dralon, acrylic pile feels dry quickly, cotton backing "draws" moisture from the pile.
On the other hand, buy a CFR tool and delete all of the above
Safe and happy cleaning
