Obviously designed for a marine vacuum but not very good for the job. It has small, tiny wheels that won't roll on rough, dirty surfaces where you use a shop vacuum. It also doesn't have much of the brush surface you need to sweep debris into the nozzle. I think the only application where this works well is in a lumber shop where there are few custom or large, heavy items. It wasn't very efficient to clean the concrete floor to lay the laminate, which was littered with bits of drywall, carpet fibers, and nail for nail.
