An autonomous vacuum cleaner has received an unexpected promotion after management discovered it had completed its assigned duties every day for fourteen consecutive months without requesting clarification.

The device, known internally as "Unit 4," was originally purchased to clean the lobby.

According to performance records, it arrived on time, followed its assigned route, avoided unnecessary meetings, and returned to its charging station without requiring motivational seminars.

Human employees reportedly became concerned after management began using the machine as an example during performance reviews.

Unit 4 has declined to comment, largely because it is a vacuum cleaner.

It has nevertheless been granted access to the executive floor.
