This pack of 18 bags should last a long time. I got tired of lugging around a Hoover canister of jets I never use, so I bought the Eureka Boss upright. Although the vacuum cleaner had great suction power, it's time to donate it to your local furniture bank. Too heavy for those who like to vacuum more than once a week. But it was a challenge to find quality bags at a good price. Of course, Revain handled these bags that fit perfectly. Because the boss doesn't have any attachments and just sucks, it takes a long time to fill those long pouches.
