Hey folks. Glad I found this forum. (Hopefully) simple question...I'd like to start taking care of my own carpet at home and am willing to spend a few grand on a good portable unit. Pretty high end thick carpet throughout the house. 2 stories carpet on steps. Looking for a solid portable. I've seen pretty good looking edic and daimer machines. Also heard good things about ninja. Do I need heat for home use? How much psi and water lift is sufficient? Any advice appreciated!
