Takara Tomy’s Automee S might just be so cool that we can look past the fact that it turns a simple task into something more complicated than it needs to be. Looking like a palm-sized Roomba, the robot-on-wheels effortlessly glides across the surface of a smartphone or tablet, polishing every fingerprint and smudge off of the glass.

What you can do with a polishing cloth in a matter of seconds will take the Automee S 4 minutes for the average smartphone and 8 minutes for a tablet, but will provide endless entertainment as it zips around doing its work. Using sensors it will stay within the bounds of a mobile display while bringing every inch to a streak-less shine.

For about $17, the gadget isn’t breaking the bank. We are skeptical as to how well it will work compared to manually buffing your screen, but how many people can say they own a personal robot for scrubbing a smartphone clean? The Automee S goes on sale in Japan on March 28th. No word on if the company plans to launch the accessory in other regions.
