It seems that the sensor only works when it wants to, despite being connected to a power source. We had to reset it multiple times in one day last week. Although, the motion sensor works much better than the voice recognition, which hardly ever works. It gets to be extremely frustrating in the middle of cooking a meal and your hands are dirty. Especially for as much as this trash can costs, you would think the sensors would be better. 

Otherwise, I love everything about it. I just wish it didn't stop randomly working.
