I got a second 2005 bagless DD vision and it was in horrible condition, so i decided to make it bagged.
How I did it,
1. Get A HEPA Kirby Bag
2. Rip off bag collar
3. take out Dirt Devil Filter
4. Superglue Bag opening to dirt cup opening
5. Place bag around suction tube
6. You now have a DIY bagged vac haha.
