This cleaner has all of the same great features as our regular Full Release® Carpet and Hard Floor Cleaner. And as always, there's no mixing, no measuring and no mess when cleaning carpets and hard floors. You'll find that our self-contained, easy-loading cartridges of specially-formulated cleaner work the way detergent works when you wash your clothing. Simply slide the cartridge into place, and the precise amount of Full Release® Allergen Control Cleaner is automatically delivered to your Oreck XL Shield Power Scrubber at the touch of a button. It's that simple.
