Greetings from GoVacuum.com,
Yes, you certainly can take off the outer bag of your Oreck and wash it in the washing machine. You DO NOT however want to put the bag through the dryer!!!!! Just hang the bag outside, and let it air dry. It is important to make sure that the bag is 100% completely dry before you use the machine again. If the bag is wet, it will cause dirt to turn to mud in the bag, and probably cause a foul odor when you use the bag.
There are 2 different types of bag systems with Oreck vacuums. The one pictured below is the older style that uses a metal clamp to hold the bag in place. The newer docking system, will be a white plastic clamp that holds the outer bag in place. They both will be removed the same way however. Simply take a screwdriver and pry off the clamp;
Once you have removed this clamp, simply pull the outer bag off. Once it has been washed, and the bag is 100% completely dry, put the outer bag back over the bag housing as far as it will go. When you put the clamp back on, it is imperative that the clamp go behind the plastic ridges, to ensure that it is tightly fastened. If the clamp is not put on correctly, this will cause the inner paper bag to fall off during vacuuming. Make sure that the clamp is in the right position when putting the bag back;
