Outdoor Rugs for Indoor Rabbits??

Hey!
I just started free roaming my rabbits in my large bedroom and I was setting up their "homebase" area when I realized the rugs that I currently have don't really work. I have 3 very small cheap rugs that I have placed under their litter box and castle so they can still manage to run around, but it doesn't work as well as I want it to. So, I want to get a new rug for that area that is around 4' x 6' and when I googled the best rugs for rabbits, "sisal" rugs kept on coming up. But, I'm not sure how easy they are to clean and vacuum, so I was wondering if I can use an outdoor rug inside my home for my rabbits instead? It seems like it would be a lot easier to clean but I'm not sure if it is the best idea. I would love to have some recommendations for rugs that are the easiest to clean and pretty cheap (but also nice looking). Here is the link to the rug I was thinking of getting: Taupe 4' x 6' Outdoor Lattice Indoor / Outdoor Rug | Rugs.com. Please tell me if it is a good idea or not! Thanks!!

I would think they'd probably destroy sisal
An outdoor rug might be OK as long as it's not too rough on their feet!

I go to home depot and buy remnants/ends--last time I got one that covered the whole room--12'x14'. It was way cheaper and I clean it off with my shop-vac.

I use carpet remnants too for my bunny.
