Zipper on Kirby Dual Sanitronic 80 bag - Whats it for?

[northwesty]

I have a few theories but honestly am not sure.

On top of that the zipper is broken on this one so it looks like it has a "problem" when it is running, so whether or not I work on this one depends on how easy it is to fix this bag -- it doesn't look too easy to replace that zipper but I haven't asked the seamstress in the family yet. or can I sew up that opening without issue? it must be there for a reason

Thanks

Brian

Inside the zipper is a pocket. At the end of the pocket is a scraper. After emptying the bag, you're supposed the put your hand in and use the scrapper to scrape the inside of the bag in order to loosen additional dirt, lint, and debris from the sides of the bag. You can also put scent tablets or clothes infused with scents into it in order to provide a pleasant aroma to mask any bad smells that may come from the bag.
