Cheapest 2.5" hose wet dry vacuum I have found this Black Friday. Unfortunately the majority of the other vacs are only 1.25" or 1-7/8" hose and won’t directly hook up to most tools, and also have lower CFM than this vac.
$59.99, but $49. 99 for Ace Rewards members. It is free to join Ace Rewards (get $5 back for every $250 spent).
