AutoStep is the effortless trash can...just a tap on the pedal is all it takes! The lid will automatically open for you, then close silently and gently when you're done using it. Or, double tap the pedal sensor and the lid will stay open for 5 minutes, while you peel vegetables or scrape food off plates. It also features an AbsorbX Odor Filter to absorb and neutralize trash odors. Powered by 4 D size batteries (not included) or optional AC Adapter (sold separately).
