Bag conversion
The assembly in the picture will work on your Omega.
If you want to buy a single assembly to get most of the pieces you need, you can buy a Kirby Heritage II or Legend II bag with the plastic Mini Em-Tor attached to it. You will need to swap the top of the Omega bag onto the Heritage II bag to make it fit. You can also remove the bag from the Sani Em-Tor on the Omega, and sew a full-length zipper onto the bag to make it usable.
If you would like to build a bag from scratch, you will need the following
Components:
Kirby bag with full-length zipper (pre G-series) (Tradition, Heritage, Heritage II, Legend II).
Kirby Heritage 2/Legend 2 Mini Em-Tor
Kirby Heritage 2/Legend 2/Early G-Series Fill Tube
Kirby Bag Guard
Kirby Bag Adaptor (only the Heritage II bag adaptor will easily fit, but the twist type and F type bag adaptors can be modified to fit.)
Cable ties
Steps:
Screw the fill tube into the Mini Em-Tor.
Secure the fill tube with cable ties.
If using a Heritage II bag adaptor, screw it into the fill tube and secure with cable ties.
If you want to use Hepa bags, you will need to purchase either a twist type bag adapter or an F-Type bag adapter. When using this type of adapter, shove it into the fill tube, secure with tape, and then add cable ties.
If you want to use the old bag, remove it from the Sani Em-Tor assembly by removing the rubber bag guard and using a screwdriver to lift the elastic ring out of the lib on the Sani Em-Tor. Wash the bag thoroughly and add a full-length zipper, as well as a strap to the top of the inside of the bag for keeping the fill tube in place.
If using a new bag, make sure the top of the new bag matches the top on the original bag. If not, remove the top from the new bag and replace it with the top from the original bag.
Take the bag and place it onto the Mini Em-Tor, making sure to align it correctly.
Hook the bag adapter into the strap inside the top of the bag.
The disposable bag can now be used in the Omega.
