Any regular vacuum cleaner will connect to a router extraction port, but there are some things to consider before doing so.  First, sawdust generated by a woodworking router is very fine, so if your vacuum is fitted with a HEPA filter, it will soon block up, risking motor burnout. Second, the hose from the vac to the router severely restricts movement. Ordinary vacs aren’t designed to be flexible enough to work with precision power tools like a router. Wet and dry vacs are ideal for this job. As the name suggests, they can deal with dust and water, handy for spillages or flooding. To see how wet and dry vacs work with routers and similar tools fitted with an extraction port, check out this video by Brighton Tools.
