ABSTRACT:
A separation assembly for separating dirt and dust from air in a vacuum cleaner, through which assembly an air flow path extends from an inlet to an outlet. The air flow path extends through an upstream separator and a downstream separator. The downstream separator includes an air-permeable filter element bounding an inner space. The wall sections bounding the air flow path in the area of the downstream separator include at least a transparent section through which the filter element is visible. The inner space is located upstream of an area outside the filter element for filtering air flowing from inside the filter element to outside the filter element.
