I have one of those fake grass Astroturf mats and it

But it "catches" dirt as well since the design of the

especially if I get snow or ice

Anyone have advice on a mat that has some big "holes"
in to allow one to pick it up and shake the snow, ice,
dirt out of it?

Try some of the offerings available at a janitorial supply store. The
professionals there often have products to make life a lot easier.
Prices will be less than an industrial supply firm and maybe a bit
more than a box store, but pretty good quality in my experience. HTH
