Hello hoovcand,
 
I don't see anything all that confusing about them and am quite impressed that Hoover UK offers models with capacities of 12, 16 and 18 pounds to help possible buyers find a machine that best suits ther needs. In any event we need more of the same added to our market if affordable.  I'm curious as to the mark-up in the process of their being imported imported.
 
For those interested, links to brochures (PDF style) can be found here.  While you're at the Hoover UK site, also check out the vacuums
