Dustaclean for keyboard crumbs, does it actually work?

Mine reaches okay but it’s kinda fiddly between keys.

I’ve had mine for a couple months and the slim nozzle does get in between the keys fine. It’s not as fast as a full size vac obviously, but it works. My keyboard had a solid layer of chip crumbs and dust from like a year of desk lunches and it pulled all that out without me having to flip anything upside down. The nozzle is thinner than I expected honestly, fits in the gaps on my regular keyboard no problem. Takes maybe a minute or two to run across the whole thing. I also use it on my laptop keyboard sometimes and that’s a little tighter but still fine. For small dry messes like you’re describing it’s exactly the kind of thing it’s made for. I keep mine in a drawer and grab it whenever stuff builds up.

Mine lives on my desk and I use it for exactly this, dry crumbs and dust around the keys. The slim nozzle does fit down into the gaps, I just sort of drag it along the rows and it grabs most of it. It’s not a one-pass miracle but it beats flipping the thing over and shaking crumbs onto my lap.

Maybe it’s just me but I’d rather have something I can leave sitting on the desk and grab without thinking. The crevice tool does reach, but I end up holding the keyboard at an angle anyway so everything falls toward the nozzle.

Mine got clogged with normal keyboard gunk after a few weeks.

The crevice nozzle is fine but nobody mentions the filter. That’s the actual issue with these little vacs. I had a similar handheld and the HEPA filter clogs up fast with fine dust, way before the bin looks full. Then suction drops off a cliff and you’re standing there wondering why it stopped picking anything up. You have to pull the filter and rinse it every few uses or it’s useless. So sure, the nozzle reaches between keys. That part works. But if you’re not willing to stay on top of filter maintenance it’s going to disappoint you within a month. The crumbs are the easy part. It’s the dust powder that kills it. I’d rather deal with a clogged filter than flipping a keyboard over though, so there’s that.
