Why not use a slightly damp cloth?

Another vote for rags.

Less waste plastic over all.

Old toothbrushes are great for cleaning keyboards and anything with crevices.

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.

I've had this vacuum for a few years. Can't remember how much we paid for it originally but it's currently $22.

We have a shared hand held vac at work that's a very expensive name brand, and when I have to use it, I always find myself surprised at how much better this one is.

It's got more attachable parts, fits better into tight spaces, and it's got a little flashlight to help you see if you're actually getting everything from dark corners.

Also the filters are washable, so you don't have to buy replacements.

I feel like the battery might not be super great, but I just try to keep it charging when not in use. Other than that, no complaints.

In the States there used to be something called a DustBuster vacuum.

Not sure what the current options are these days, nor how it looks in other countries. (i'm more of a wet rag, broom, and feather duster-type)

Dirt Devil Scorpion Plus. Fairly powerful, and corded so no batteries to mess with.
