The Cadillac of ash vacuums! Similar to the popular Cheetah II Ash Vacuum, the Cougar's ultra-quiet design and superior cleaning power make this vacuum the best of the best. This patented machine is designed for conventional stoves, pellet stoves, and fireplaces, and will make cleaning those pesky ashes a breeze! Please note, this unit is designed to pick up ashes once they have cooled. The nozzle of the hose is approximately 1" in diameter and is not designed to pick up coals or granules of coal.
