I'm a new user of my Bissel carpet shampooer. I've used other shampoo serviced, even professional. Nothing has ever worked as well to not only clean the white carpet in our heavy traffic area, but the machine and this chemical has restored it to new looking and, with the scotch guard, will hopefully keep it easier to clean We vacuum regularly and take care of our carpets. I like the way this chemical leaves the surface feeling non sticky too.
