Filter or Bagged vs Bagless Vacuum Cleaners
As with most things in life, there is really nothing for free. The two most claimed advantages to bagless vacuum cleaners are lower operating cost and better performance. In reality when it come to cost issues, all vacuum cleaners must filter the exhausted air they use to carry the dirt into the collection area. Otherwise, they would just simply pick up dirt from the floor and spit it right back out into the room.
