Nylon rope, not pleasant grip, picks up everything in its path. when AC drags on the ground (it's still the goal) was in 10min to remove the branches, leaves, dust small stones, insects, etc ... Very very fine cord, which unravels quickly.
I want to clarify that this product (which is admittedly very poor), NOT ALL THE REPRESENTATIVE OF THE BRAND KARLIE who generally very good articles. But this one, I am very disappointed.
