"One metric ton of methane produced by the fermentation of food waste can generate 100 degrees of electricity." The accumulated food waste can last up to 3.5 hours in 3 days and can last up to 8 hours in 7 days.(The amount of food leftover per day is calculated based on 700 grams.)
"Food Robot Vacuum" display the stored power, control the sweeping robot, and display the amount of garbage in the dust box. When the sweeper returns to charge, it will automatically clean up itself. Food waste and dust are cleaned up once a month instead of frequently pouring food waste and cleaning dust box.
