It is common to see a robot vacuum cleaner with a circle shape. Nevertheless, when it comes to cleaning corners, it is hard for these ordinary robot vacuum cleaners to clean that area perfectly: the round shape doesnt fit to the angle of the room. Water drop shaped vacuum cleaner, however, clean the corners of the room easily. This idea is originally from the shape of a water drop. To be specific, water has no certain shape so it could fill any kind of container or corner of the room as well.
Such simple but creative change will help customers ease the frustration of cleaning and will experience so much more convenience.
