The first sensor trash can from simplehuman with the sleek look and durability of stainless-steel. A quick wave of the hand over the lid's sensor zone triggers the can to open. Thanks to a smart multi-sense(TM) system, the lid stays open long enough for you to finish the job, then closes automatically. Made from durable stainless steel and black polypropylene. Sensor on lid detects hand motion directly above and opens lid automatically for truly touchless operation. Once the lid is open, the sensor becomes more sensitive to motion, so the lid won't close before you're finished. After 3 seconds of continued activity, the lid automatically opens wide and switches to a 30-second stay-open mode - good for longer chores. Brushed-stainless-steel finish is fingerprint-proof to resist smudges and wipe clean easily. Replaceable charcoal filter in lid neutralizes odors naturally. Bag-tuck feature hides excess bag. Space-saving rectangular shape with internal hinge sits flush against wall. Runs on six C batteries (not included).
