A vacuum cleaner has an elongated porous outer bag for holding a filter bag over an air outlet. A hanger within the outer bag is positioned to suspend the outer bag from the vacuum cleaner, as well as to hold a pocket within the outer bag, so that spare filter bags may be held within the porous outer bag.
