You may be wondering what on Earth you're looking at, particularly if your introduction to this whole phenomenon is pictures like this one.
Truthfully, this is just one of those brilliant moments where everything came together. The shark outfit for Halloween, the Roomba out for its daily floor cleaning, the duck on the loose.
The cat is having fun. It wouldn't have climbed onto the Roomba if it wasn't. The human owner filming is certainly having fun. How could you possibly watch that playing out without dissolving into fits of giggles? (You'll get the chance to find out in a bit. I'll include the YouTube video here.) The floor is getting cleaned.
The only creature I can't vouch for having quite a wonderful time is the duck. But it wasn't harmed, and its owner did dive in to calm it shortly afterwards.
You too could recreate this scene at home. Or many more hilarious moments like it. You just need a cat and, of course, an iRobot Roomba.
