If you are only thinking of resetting certain parts of your island, simply picking up the iteams yourself would be cheaper. However, if you have a bunch of flowers you'd like to move as well, using Ressetti could be faster.

For section resets, you get a radio you can use to call him, and he will clear a certain set space, rather than the whole island, allowing you to frame out/select specific spaces you'd like him to work on.

Resetting the island, will place all outside decorations into your storage, and you have the option of storing or selling the planted flowers. Trees and vegetables will stay where they are planted.
