The Sebo AUTOMATIC X models are the most technically advanced and uniquely easy-to-use vacuum cleaners in the world! The 15-inch X8 features truly automatic height adjustment, an LED headlight, and an extra layer of micro-filtration. An electronic controller measures the resistance of the spinning brush roller against the floor surface and then signals up or down adjustments, to ensure optimal performance on both carpets and hard floors. The user is alerted to clogs, a worn brush, or a full bag, and the vacuum automatically shuts off when brush obstructions occur. The X8 also has an instant-use cleaning wand and suction hose, a lifetime belt warranty, tool-free brush roller removal, a 40-foot power cord, three on-board attachments, and excellent pet hair removal.
