cordless shop vac

[big e]

I have a new-build outhouse that I like to keep tidy for the ladies.
Can anyone recommend a cordless shop vac or dust buster type thing that you like? Something with attachments would be nice to get into the corners and around the bookshelves and artwork.
Carolina wrens LOVE to make nests in there and you can't clean it up without bits of moss and stuff getting all over.
I, and the ladies, thank you.

Question:

Why do you have such a big window right at the "business end" of the outhouse???

For the light, and for the view, of course.
