The Dyson Mattress tool attaches to the wand or hose on your Dyson vacuum cleaner to remove dirt, allergens and dust mites from mattresses and upholstery.The front and back edges gather, ball and release fibers into the airflow, where they are sucked away. The top is angled to distribute suction power evenly across the tool. A 45 degree neck angle and rounded front make it easier to push across fabric, carpet pile and mattresses.
