3M dust remover is a great tool for things such as removing dust and hair or crumbs from keyboards or other electronics. I use mine mostly for my keyboard on my laptop, which unfortunately catches a lot of crumbs and dust and pet hair. It gets a lot of crumbs because I eat a lot at my laptop, and my dog sheds like crazy so there is always pet hair caught underneath the keys. Sometimes so much gets caught I can't even type correctly. Enter the 3M dust remover, which uses a burst of compressed air that pushes out all the nastiness underneath the keys, out and away. It uses a long tiny tube that you can attach to get deep underneath the keys or into other crevices that you are looking to clear out. I also use it on things such as my Xbox, TV and on my desk. With the tube attachment its easy to get into tight areas or areas where your duster or vacuum might not be able to get to. Its great for electronics which is what most people use it for. I definitely recommend a dust remover tool like this in your cleaning kit, because it doesn't use any liquids and therefore is a lot safer to use for electronics or delicate items.
