I like those dry Swiffers a lot ... can't use the wet ones b/c of Fergie running around ... might get the chemicals on her little paws. And those Swiffer dusters are what I always use on the job b/c they're so effective! They are not cheap either ... was shocked to see what they charge for a large box of them ... almost $1 apiece for the duster part.
I just read yesterday you could replace the sheets with some other cloth, regular rag? I forgot what.
