living robot vacuum cleaner

You recently bought a robot vacuum cleaner and set up its charging station next to your desk. Every day at 12, it would come off the charger and scrub the floor with its brushes.
A week after buying it, you found a strange book in the storage room. One chapter described how to animate any object. You didn't believe it, but decided to try it out of curiosity. You cast the spell that was written, and nothing happened. You continued writing something on your desk, frustrated, when a moment later the robot came off its charger and went to clean up. It was strange, because it was only 10 o'clock. You thought it was just malice and wanted to return it to the station. When you turned around, you saw its frightened eyes darting around the room. And it looked at you. It was frozen and motionless.
