When it comes to the automatic ones, they will feature a sensor and when you will have a trash bag that will be ten inches above it and at a one hundred and thirty degree angle from it, the trash can will automatically open. If you are using it in normal parameters, then you will be able to use this amazing feature for 6 months until the batteries will run dry. This collapsible trash can works with 4 D-size batteries.
Lemon or Lime Peels: Just put some lemon or lime peels into an uncovered container and leave them inside the confined area for a couple of days. The citrus smell will naturally replace the bad trash can smell.
