Vacuum Cleaners Discussions

It's for show and effect.  Means nothing.  It's the clean exhaust air that matters.  If you put a brown sandwich paper/plastic bag in the vacuum, you'll have a 100 percent sealed system.  Air in, no air out.  Blow up a snadwich bag, air inside sealed closed, and burst it.  But, using a bag like this in a vacuum, and the motor will overheat and burn out in short order.  A worthy vacuum lets air and dirt in, contains all the dirt, and lets the fresh air out.  That is the MIELE forte: 100 percent sealed system.  Motor lasts fur immer.
