my DC wont pick up screws either. probably better that way as if you didnt have a separator in between the screws would hit the impeller, damage it or worse create a spark and ignite your sawdust after you left your shop.
i use my shop vac to clean to floors, but i did have to 'try' the DC. shop vac wins that round.
