The BISSELL Pet Spot lifter for upholstery and carpet is specially formulated to remove tough pet stains like urine vomit and mud. The convenient built-in easy to use fabric-safe brush cleans dirt from hard to reach crevices and around contours. It also includes a patented odor elimination which discourages pets from resoling the same area. ow are the BISSELL Pet formulas different than other BISSELL cleaning formulas. The BISSELL Pet Formulas have an added ingredient; enzyme producing bacteria. Enzyme producing bacteria remove urine feces and vomit from the cleaning surface completely and permanently by consuming the food source. By removing the urine feces and vomit bacteria have nothing left to feed on. Bacteria simply die off. If you didn t remove the urine feces or vomit new bacteria will eventually start feeding again with the addition of moisture.
