I'm a 92 year old amputee widower living alone with my 12 year old partially paralyzed dog Lady. It's important to us both that things work like they're supposed to. Because of her condition, Lady can have an "accident" and never know it Bissell's PET Stain & Odor Upright Carpet Cleaning Formula does an outstanding job on those "surprises." It really does what the ads say every time. In 5 minutes you would never know there was an accident with no trace of odor or stain. It's easy to tell that Lady is as pleased as much as me with the results. After the job and Lady's inspection I get a hand licking thank you from my big Belgian Tervuren. We couldn't be more pleased with Bissell
