How to change the garbage bag daily.

Open the front gate, pull the garbage bag out till you get where you need to cut, then cut the bag with the hidden blade on the inside gate. 

Throw the garbage away then tie a knot at the garbage bag tail. Then repeat the above process the next day till you run out of this roll of garbage bag. Then you can open the upper lid by pushing the oval button then put a new roll of bag between the outer barrel and the inner barrel, done!
