Differing from past traditional foot-operated bins, this series of sensor dustbins use infrared technology for convenient use. 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 cell batteries and the bin is ready to use. With a durable stainless steel 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, and please understand the small measurement errors.
