Since I'm poor (but have expensive taste spelled F-E-S-T-O-O-L), I just attached a piece of 3/4" EMT (elec conduit) to my vac handle and then bent a piece of 1/2" EMT and put it inside the 3/4". A couple pieces of velcro strap later(holds hose and cord to 1/2" EMT), and I've got my $20 vac boom arm, and it rotates (the 1/2" arm inside the 3/4" upright) to give me more freedom and reach with the tools.
