The sturdy ESSENTIAL G is a powerful, technically advanced, upright vacuum cleaner that will provide years of reliable use! It has four-level, manual brush height adjustment and a 12 inch power head width. They clean carpets and hard floors and have excellent pet-hair removal. The G series also features an electronic controller that acts as a brain, alerting the user to a worn brush, or when brush height is set too high for optimal cleaning. It even shuts off automatically when a full bag, a clog, or a brush-roller obstruction occurs, which protects the motor, belts, and carpet from damage. They also have an instant-use cleaning wand and suction hose, an exterior housing with a scratch and scuff-resistant matte finish, tool-free brush roller removal, a 40-foot power cord, three on-board attachments, and protective rubber-coated wheels.
