Commercial vacuums are designed to withstand daily use and are warranted for use in a commercial setting. Typically, the motors are designed for higher performance at lower amperage to conserve electrical expense. They have heavier, longer power cords for vacuuming large areas without the need for frequent replugging, and heavy duty agitators to help withstand daily vacuuming in a commercial setting.
Note: Features vary from model to model. Check individual model specifications for details.
