The heavy-duty Electronic 370, a two-motor vacuum with separate suction and brush motors, is SEBO's quietest upright vacuum! It is designed to provide many years of trouble-free operation and features an aggressive power head with manual brush height adjustment and a convenient instant-use cleaning wand and suction hose. In addition, the vacuum features an electronic controller that not only alerts the user to problems such as clogs, a worn brush, a full bag, brush obstructions, and when brush height is set too high for optimum cleaning, but it also automatically shuts off the brush roller when it is jammed to protect the motor and belt from damage. This is a perfect vacuum for large carpeted areas.
