It's always nice when you can cobble together some of your scrap and make something useful, it's a small victory against all that people that want you to live the spartan life, 3 objects per room. Fuck 'em. My junk is MY treasure. I have a tiny compressor I use for painting and inflating tires, I use it mostly to work with bikes so the size doesn't matter much, and you're right, it's so damn useful, I get shit done so fast and then blow air on the floor and bam, it's acceptably clean in a second.
