Pets can make hidden messes that you can smell but can't see. The "exclusive" 3-inch scrub brush on the Dirt Devil Portable Extractor comes with a black light LED to illuminate unseen pet stains so that you can target them with the scrub brush.
There's a 56 oz. capacity tank on board, with up to 44 oz of dirty water holding as well. The set comes with 8 oz. solutions of Dirt Devil Pet Stain and Odor Remover, and Dirt Devil Carpet & Upholstery Cleaner and Shampoo.
Normally, the Purpose for Pets Portable Extractor runs $100; currently there's a special that combines the Extractor with a Broom Vac for only $130, a savings of $23 on the combination, and it includes free ground shipping.
