• A touchless automatic motion sensor trash can.
• You do not have to touch any part of the trash bin just to open and close it.
• No contact trash can means lesser chance on contaminating yourself with disease-causing bacteria and viruses
• they are actually quite practical. They open and close automatically, keeping germs and related shmutz off your hands. Those with mobility problems may find the automatic feature more convenient than foot-operated models.

With a motion sensor trash, you will automatically open and close the lid of the bin without needing to touch the bin physically. When the infrared motion sensor detects the motion of your hand or foot, the lid opens automatically.
