You can open it with knee beed sensing or hand waving sensing, Don't have to step on anything or touch anything to get it to open the lovely no touch trashcanThere's a sensor that picks up when you are close to the aut trash can then opens the lid, waits about 5 seconds and closes it. If you want the can to stay open so that you can empty plates or spend more time tossing stuff into the can you simply hit the "open" button and the lid will stay up. You can turn the motion off or on with just the press of a button. This isn't a cook item, but no cook should be without it, saves lots of cleanup timeThe touchless trash bin has a battery-powered lid, operates on 2 AAA batteries (not included), so you don't have to touch it to throw something away. But if you choose not to put in batteries or you forget, you can still use it like a regular trash can lid and open it yourself. It also has a liner holder which holds your trash bag in place, so you not have to worry about the bag falling in with the gross trashIt's a large capacity electronic trash can, 3.6 Gallon, 8.6 inch length * 8.6 inch width * 11 inch height. The mouth is wide so emptying a plate is not a problem.The only issue that with the motion sensor kitchen waste basket is that if you fill it too full, it can dislodge the battery compartment cover and the batteries will fall out. If you are not noticed this had happened, your battery compartment cover would have been gone forever as it had fallen into the garbage canJust be sure you don't let moisture condense under the butterfly garbage can's lid or get water on the lid. If water gets inside the electronic components, the motion sensor will stop working. Had to leave it out to dry completely before it started working again. And if you plan to put it in a location that is well "trafficed" this might not be a good little sensor trash can because the sensor may activate without wanting to throw anything away into it
