AUTOMATIC X models are the most technically advanced and uniquely easy-to-use vacuum cleaners in the world! Available in two power head widths, the 12-inch X7 features a 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 X7 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.
 
The three-X7 Premium models also offer the user a choice between two modes of brush roller aggressiveness! The default setting is perfect for most flooring types, but by pressing the Brush-mode Button located on the power head, the spinning brush roller is allowed to attain greater resistance against the floor surface before upward height adjustments are made, which causes deeper brush action on carpets and rugs. However, the X8 does not have a Brush-mode Button. The X7 Premium PET also includes a turbo brush, a nine-foot extension hose, and a microfilter that absorbs pet odors.
