Equipped with a powerful yet quiet 12 amp motor, this upright vacuum cleaner provides exceptional cleaning results and improved indoor air quality. The unit automatically adjusts to the proper setting for just about any carpet height, while its HEPA filtration system captures 99.97-percent of dust, allergens, and small particles, so only clean air gets expelled into the home. The vacuum's motor-protection system channels dust and dirt particles directly into the vacuum bag, promoting long life and more efficient cleaning for the fan and motor.
