This is probably one the best practical invention I have seen, I have always managed to flip or break the trash cans with step lid opening mechanicm, but for this one they were smart. You put your foot in the sensor area at the bottom and it will open, there is also a little mechanism to keep it open if you need to while cooking. It can operate on a power adapter on a few D-Cell batteries. I love these types of practical inventions because it makes things simpler around the house. I remember just buying a trash can with an open lid so I can just toss things in it while cooking to keep the are clean, but later on the smell of whatever you threw would still be there unless you throw out the trash right then and there. This gives you an alternative option and it just makes things more convenient.
