I am very pleased with your Keeler bag less conversion. I can’t believe the dirt and dust this thing traps. Best of all, it is such a simple and efficient design. The unit appears to have an authentic Kirby coupler that connects to a well built canister and filter device. With that, the filter canister easily attaches and removes.
In reality the price is just right for the materials and design. You couldn’t build anything simpler and more effective. In fact this is less expensive than replacing the bag and fill tube. I strongly recommend this to anyone who has a smelly old Kirby bag.
