20L (Internal volume 15.5L). High-quality stainless steel bin with stylish design. Differing from past traditional foot-operated bins, this series of sensor dustbins use infrared technology for convenient use. The lid opens by waving your hand within 15-20cm of the infrared motion detector. It will sense your approach, activating the motorized lid for your convenience. The lid will automatically close after a few seconds of non-usage. The units can also be opened and closed manually by pressing the buttons on the lid. These bins are battery powered so no wiring is needed. Just pop in 4 AA batteries and the bin is ready to use. With a durable mirror finishing body, they ensure a longer service life and are stylish and beautiful in all types of interior settings. Please note batteries and bin bags are not included.
