Where can I find vacuum patents?

[funnynet123]

Does anyone know where I can find the patents to specific vacuums?

Google Patents. I've found several old Electrolux patents there that I found interesting.

Yeah, google patents. It's a bit hard though. Firstly, all the paperwork is digitized by algorithms, so typos are abundant, and make searches hard when, for example, google read the word 'vacuum' as 'vacwm.' Second, patent dates are confusing. There's the application date, the publish date, and one other, can't remember. So if you're looking by date, you have to search by all three date types. Then of course, not all patents are applied for by the manufacturer, often it's by a person who worked for them, or another company entirely. And then there's patent jargon. Where a vacuum might actually be a 'suction machine.'
