Mark is friendly and efficient, cleaning 4 area rugs, one wall-to-wall carpeted room, and 4 oversized floor pillows in just a couple of hours. Our carpets were embedded with construction dust from a recent remodel, and hadn't been cleaned for years before that. No exaggeration, the colors and surface of the carpets look almost new (and are between 10-50 years old). Best of all, he used no smelly chemicals and we could resume walking on them within an hour or two. I am a believer.
