Trash can with motion sensor. Infrared fields detect areas above and in front of the trash can, allowing it to open automatically with just a wave of your hand. Smooth and consistent operation: The planetary gear system ensures optimal speed and torque control, enabling the lid to open and close evenly. Extremely quiet: At just 52 dB, this trash can is 50% quieter than competing products. Simple and clean: The outer lid opens to provide access to the bag - you don't need to remove the container lid or handle a bucket. When you're done, the lid closes automatically. Bag compartment: Store the bags where you need them. For quicker bag changes, simply pull the bag directly from inside the container. The transparent nanosilver coating protects the stainless steel from fingerprints and germs. Battery type: 4x AA batteries (included with purchase).
