Cleaning floor vents

[Doug and Anita]

Can someone tell me how to clean the floor vents in our Monty? I know we can unscrew them and vacuum them out that way, but Doug said we will end up stripping the screws after awhile. I keep thinking that if I could find something small enough to fit between the slats and I could get the vacuum in there that that might do the trick, but haven't found anything yet. We have a dog and cat with lots of loose hair and it seems to collect in the vents!
