The vacuum bags are the most important part of the various additional components of the vacuum cleaner. The Miele vacuum bags have special features curated in them that offer nine layers of protection. This layered protection prevents the fine dust particles, allergens and even microscopic particles from escaping away from the dust bag. Miele vacuum bags are different from the conventional vacuum bags because they have twice the life of any conventional vacuum bag. The one feature which is not found in the cleaners of other brands in the same category is the auto-shut mechanism which prevents the dust from moving back or escaping from the cleaner when the vacuum cleaner is opened.
