Steam cleaning is something I always take my time with. I usually wait till everyone is in bed and then get it done so no one walks around while its drying. The deep clean works really well, I go over each section twice to ensure its getting in there. Takes about an hour and a half to two hours to dry entirely out, hence the night time usage.
Its easy, just time consuming. Takes me about 45 minutes to do my living room and then down the hallway, with moving furniture to get under everything.
