How do home vacuums work?
user
Some home vacuums have a little bristling brush that brushes across the carpet to pick up dirt, dust, and other particles.  The vacuum can be connected to a hose that goes outside, so that the dust and dirt can be sucked outside.  Inside, the dust and dirt are carried into a removable bag.  Usually, it’s easy to get these bags replaced, so that vacuuming can be done on a regular schedule, since the bags will fill up over time.  If you have a hardwood floor in your house, you’ll have to vacuum carefully to avoid scratching the floor.
