Sounds too good to be true?
Even cats like robot vacuums:
You can get a robot-vacuum (for a price… usually around 40-50,000yen).
You can see a list of prospective robovacs here.
They’re chunky, circular machines that whizz around your room and suck up the dirt.
They usually have sensors to avoid bumping things… as well as a home-dock that they can return to when they’re done.
Totally unnecessary and impractical… but IT’S A ROBOT!
