I bought my small handheld vacuum at Walmart. Hubby has tried to use it several times and I said no no no! Get your own! lol
Some Walmarts also sells the small attachments in the hardware department for about $8 or so. I got mine from a sewing machine shop in town but it didn't fit my regular vacuum and the miserable place would not take it back so I bought a handheld vac which does work and even though it ended up costing me a lot more in the end, I know it will save me a lot since I can clean it regularly...
