Unless you have experience in cleaning older wool carpets, i would recommend professional cleaning. Most places charge by the square foot so it's pretty reasonable. As far as the linoleum rugs go, they are going to crack some; there's just no way around it. Once the backing dries out it becomes extremely brittle and when you lift it off the floor, it starts cracking. You will most likely have to cut them up to transport (unless you have flatbed trailer, lol), as they will not roll up. Try to get a good section that looks like an intact representation of the whole rug, especially if you're looking to resell them. Are the rugs loose on the floor? That will improve your chances 1000% of getting them out in the best condition you can. Please post pics of your finds after you get them - old lino rugs are such a treasure. Good luck!
