The AUTOMATIC X is the world’s most technically advanced and uniquely easy-to-use vac-uum cleaner! Available in two power head widths, the 12-inch X7 and 15-inch X8 feature truly automatic height adjustment, using an electronic controller that measures the re-sistance of the spinning brush roller against the floor surface to signal up or down adjust-ments, which ensures optimal performance on both carpets and hard floors. The user is also alerted to clogs, a worn brush, or a full bag, and the vacuum automatically shuts off when brush obstructions occur to protect the motor and belts from damage. The X also has an instant-use cleaning wand and suction hose, a lifetime belt warranty, tool-free brush roller removal, a 40-foot power cord, and three on-board attachments.
