Abstract
This invention relates to a bagged vacuum cleaner, i.e. to a vacuum cleaner in which dirt and debris is collected in a disposable bag. The vacuum cleaner () has a body (), the body having a dirt-collection chamber (), a motor () and an impeller (). The body also has an inlet duct () upstream of the dirt-collection chamber, the inlet duct being connected to an inlet tube () adapted to fit to an opening of the disposable bag. A wall () of the inlet duct adjacent to the inlet tube () is transparent so that a user can look through the wall and into the inlet tube to observe whether or not the bag is full.
