This is true in a certain nonspecialized sense but thanks to thermoclines, pynoclines, haloclines, and various other physical phenomena that basically amount to scientific voodoo, there are parts of the ocean don’t actually intermingle with each other despite being ostensibly physically connected.

I take the opposite approach. I use the puffer bulb that came with my camera cleaning kit. Then I can vacuum the floor.
The danger with vacuuming things off of your desk (or at least my desk, which is inevitably strewn with tiny screws, 3D printed parts, bits of fountain pens, etc.) is that you’ll suck up something that you’d really rather you hadn’t. And then you have to get it back.
I can recommend you avoid those sub-$10 USB mini vacuums from China you see everywhere. I have one. It’s practically worthless.
