This wildly famous video of a duckling playing with a cat in a shark costume demonstrates ... well, it doesn't demonstrate much of anything.
But there are plenty of things about our vacuums that we can learn from animals.
Before it gets vacuumed by its owner, this duck first lays on its back in preparation.
The duck also knows what many vacuum owners don't: That the crevice attachment on your vacuum is most likely underused, and more versatile than you think.
This pet squirrel, named Mia, sees a vacuum hose as a playmate.
Many vacuum hoses can be replaced by the home user. That's a good thing to know in case, say, Mia here decides to use this one as a chew toy.
Some cats, like Bobo here, really, REALLY love to be vacuumed.
In fact, many vacuums come with attachments specifically geared for vacuuming hair from a live animal.
"How to help a bunny lose weight?" the poster of this video asks. How about strapping some carrots to a robotic vac?
It's a cute thing to watch, but the bun is probably setting off the object sensors in the vacuum, confusing the bot and preventing it from doing a clean sweep.
Golden retriever Bailey sleeps so soundly that the robotic vac's sensors have categorized this dog as a wall.
Does this photo really need a caption? No. No it does not.
But we can't help but wonder if the cat's tail is leaving behind as much hair as the vac is picking up.
All this kitten wants is to make the kitchen floor shine.
Most robotic vacs start off by cleaning in an outward spiral before finally arriving at the perimeters of a room. That kitten is probably light enough to avoid pressing the on/off button under his little paws. But if he wants to keep riding this vac, he'd better watch the kibble intake.
This parrot literally backed a vac into a corner ... and won.
Eventually the vac will have to return to its charging station if the parrot wants to go another round.
Where is Pluto the guinea pig headed via Roomba? He's chasing a poodle just offscreen.
If the poodle is smart, it's made use of the vacuum's virtual wall units to set up a perimeter.
In response to the popular shark Roomba cat, a VFX guy posted a video of a CG shark in a tiger costume ... riding a robotic vac, of course.
Note that most robotic vacuums cannot handle wet spills. In fact, some are really good at spreading them around. Shop for a robotic vac carefully if your house is vulnerable to doggie accidents or other damp disasters.
This English bulldog pup, named Tank, is learning how to chew ... courtesy of a robotic vacuum.
Unfortunately, Tank is so into his incredibly expensive chew toy that he doesn't know he's headed right for a wall. A robotic vac does have at least a couple of wall sensors, but the sensors don't necessarily slow the vacuum down. They just tell the vac to stop or turn.
