The write up beneath it says,' The worst areas had a light treatment again to remove the small amount of soiling remaining,' so why use an unfinished segment and not the entire process from beginning to end.
A video is like a book or film, an unfolding story that begins in one place and ends in another. Goron's story is, 'How I saved this carpets life'. Doctor Goron carries out emergency surgery, using all of his years of experience, hi-tech tools and medicines and struggles against the clock to remove gallons of filth and bacteria from the patients diseased fibres, while the patient, an ageing Wilton from Axminster clings perilously to life by the skin of his weave.
Tell that story and it would be interesting.
No disrespect intended to Goron, by-the-way.
