I would get either 200 psi with dual 2-stage vacuum and heat or 500 psi with dual 3-stage vacuum. I personally use 500 psi portable unit its heavy but does the job excellent. if you are worried about damaging carpet or upholstery then use DFC 105 i have never ever had any problems with it it is not strong enough for very dirty carpets but does a good job.
