I'm wanting to get the 2gal Hercules from Harbor Freight. $85 and can be used corded or cordless. 5.0Ah battery and charger is $100 right now so for $185 all in you have a new battery line and new vacuum. I've been slowly getting more Hercules tools on top of my Milwaukee and I've loved every one so far.
I got a Hercules vaccuum from harbor freight
Wow. Expensive. I got a battery powered shop vacuum for under $100 at Harbor Freight. I already had a bunch of Bauer tools, so I had batteries for it.
I use the Ryobi, and recently got an HF Hercules with HEPA filter - has a hose, too.
