Patent abstract

The invention is floor care appliance such as vacuum cleaner having two embodiments of a dirt particle separating and collecting system removably inserted into a recess in the floor care appliance's housing. One embodiment of the dirt particle separating and collecting system includes a translucent dirt cup having an apertured between two adjacent dirt particle collecting chambers and a primary filter located in one of the chambers. The other embodiment is a translucent bag container and a filtration bag. The filtration bag may or may not be disposable and may or may not have a HEPA rating. When either embodiment of the dirt particle separating and collecting system is installed in the housing, a portion of the dirt particle separating and collecting system is not visible in the area in the front of the floor care appliance. Another portion of the dirt particle separating and collecting system is visible in the area in the front of the floor care appliance. The dirt cup and bag container are translucent so that their interior volumes are visible from the exterior. This allows a portion of the particle separating occurring in the dirt cup to be visible, or in the case of the bag container, a portion of the filtration bag to be visible.
