I don't know how the Cricut mats are laid out, but the one's from Graphtec have about 1/2" down each side that has no adhesive on them. This is where you would set your rollers. If the Cricut mats have adhesive across the entire surface, you may have a problem.
The Graphtec sheets will work in any cutter and you can get a pair of the Graphtec OEM sheets here:
Consumables
The CraftROBO Pro sheets are larger than the CraftROBO (non-Pro).
I like the OEM sheets better than any of the aftermarket stuff I've used. The adhesive on the aftermarket stuff is realy agressive and I've had problems with the paper tearing on some of the more delicate designs. The Graphtec mats seem to hold fine and realease clean.
