The rodent's movements with the ball are fed to and analyzed by a complex set of sensors, which then guide the actual vacuum device to mimic the animal's speed and direction. You can see where this is going: it's a clever ploy to then get you to buy a second robot that would automatically feed, water, and clean up after the hamster in the first robot."
