I get down hands and knees with a scrub brush usually a liquid spray safe for carpets or reg. dish soap.I also have a Bissel Green machine works great.Having large areas to clean wears on the knees but I don't feel it gets clean enough with a machine unless I do the work & elbow grease.Just this past week I used Resolve powder scrubbed like crazy all my rooms with carpet looks great.Now just to keep the drinks & food in the klitchen shoes off when entering my home is another task
