Does stopping to lift the lid off your trash can kill the tempo in your kitchen? Get the flow back with Simple Human's Sensor Can ($225-$275). This hands-free and foot-free lidded can is the company's most efficient can yet. The Sensor Can is integrated with a smart sensor called Multi-Sense, which recognizes when you're just walking by, when you need to toss out trash, or when to keep the lid up during extended tasks.
