Basics

This was a Cyclonic Seperation Technology that follows some of their Vacuum Cleaner's Primary and Secondary Cyclones
It supposedly was able to filter dust down to HEPA standards all with no filter (ALTHOGH one was added as a failsafe)
If it could be replicated, it would be especially interesting in that it would reduce/eliminate the need of filters, which makes any design more cost effective (in theory at least) and also uses more Appropriate Materials
