Touch-free is the most efficient way to wash your hands — no smudges left behind. Clog-proof tubing pump ensures a precise and consistent flow, and the silicone valve prevents messy drips. To control the amount of soap desired, you can position your hand up close to the sensor for a little soap and farther away for more. Wide refill opening makes refills fast and easy, and there's a QR code under the lid so you can reorder soap in a flash. It's also waterproof for easy cleaning. Rechargeable with included charging puck — one charge lasts up to 3 months. Use simplehuman soap for optimum pump performance. Also works with hand sanitizer.
