As needed, yes it will absorb urine and can be spot cleaned when it comes to feces however even than ammonia will build up which means it will have to be cleaned up, to it all comes down to the species you keep and their size and how much they urinate (I prefer coco husk for smaller species for BP and bigger species I prefer Coco chips)
.
BTW there are similar options that are significantly cheaper, but there will be a little prep, the high price comes from the fact that it is prepped for you and the name on the bag.
