Oreck's docking upright vacuums are equipped with a bag docking door. The dust bag is slid into position on the bag docking door, and the door is then snapped into place. The system is designed to lock the bag in position, thereby avoiding the escape of any dust.
Changing the bag on an Oreck docking vacuum begins with the complete unzipping of the cleaner's fabric bag. This reveals the cardboard collar of the dust bag to be removed. Pulling the collar releases the bag drop door, which hinges downward. The bag is freed by pulling the cardboard collar upward. The cardboard collar of the new dust bag is then slid completely onto the bag dock door, which is pushed until it snaps into position.
Oreck's older upright models are not equipped with the docking system of dust bag installation. Users of these machines have to slide the bag into position themselves and ensure the bag is securely locked in place. There are two lips, A and B, on the connector assembly within the outer permanent dust bag. The bottom of the disposable dust bag's collar opening is hooked under Lip B. It is then pulled upward and snapped over Lip A. When full, the bag is removed using the reverse procedure.
Dust bags for Oreck's docking and non-docking vacuums include a range called "Saniseal." These bags seal automatically when removed for disposal, guarding against spills of dust within the home. Some of the company's dust bags also feature high efficiency particulate air filtration.
