When changing or emptying your vacuuming cleaner bag, run the vacuum for 30 seconds to push any residual dirt left in the machine, into the bag. It is a good idea to put a piece of duct tape over the hole where to bag attaches to the vaccum, before pulling out the bag. This will prevent a cloud of vacuum cleaner dust from your face.
For those of you with a reusable cloth bag or a plastic bin, it is a good idea to work outdoors. Place the bag or bin inside of a trash bag and shake out the dust. Before replacing the bag or bin, rinse thoroughly with hot water and then let it air dry.
Hint: When your bag is half full, the vacuum loses suction power and will continue to work harder and harder, the more full your bag becomes.
