I like how the title is phrased as if this constitutes the cat hoovering, ie the cat is doing the work... I guess this is about as close as a cat doing actual work as u can get tho.

10 years ago, a cat riding around on a roomba was a wacky viral stunt. Now it's just what cats do. If you can't get your cat to ride around on your roomba, you take it back to the shelter, and they put it to sleep. Amazon Prime will deliver a roomba and roomba-trained cat in one package, and they'll do it within 24 hours.

Looking at my apartment right now, it's obvious that I have too many cats, not enough robot vacuum cleaners.

If you can watch this for 9 hours, you're already relaxed.
