I have this hooked to a Sears Shop Wet/Dry Vacuum.  As others have noted, the attachment size is a little "non-standard", probably due to the fact that the hose fits over the tools instead of sliding in them.  Nonetheless, the hose and swivel are easy to use and the material makes for very efficient pickup.  I also like the claw and crevice nozzle.  They are a bit small for small spaces in my small car, but they are great for going over floors, seats, and jobsite pickup.  Definitely recommended over the stock hose that comes with most shop & wet/dry vacs.
