Our Pet Stain Eraser™ PowerBrush cordless portable carpet cleaner is always ready to remove tough pet messes, so it's great for families in that little mess maker phase of pet parenthood. We engineered it with a powerful rotating DirtLifter® PowerBrush to loosen, lift and remove tough pet stains. This cordless machine has a lithium-ion battery, so you get an extended run time. Plus, unlike other portable carpet cleaners, you can store the formula right in this machine's tank when it's not in use, so there's no hassle and no mixing the formula with water.
