My vacuum cleaner is a thousand years old - or at least 30-40 years old so I didn't think we'd even find bags for it. We bought these and they work fine. I think the suction issue has more to do with the age of the vacuum than the bags themselves. The bags are easy to install, just place them in the vacuum and close the bag. They're a good size too, so they last a while and give you more bang for your buck. I will definitely buy again.
