I purchased another model with just garbage, also sensor/voice control, and I just had to stick with that same technology when I purchased my second container. I love it, guests love it, the kids love it! Super convenient when something is dripping and you can just say "open can" on your way towards it, just love the motion sensor and voice command. I find myself now waving or talking to all others garbage when outside my home, makes me laugh! Super quiet, quick, reliable, custom fit liners with the liner storage built in! simplehuman is #1, I will never change
