But here is why I put one on anyway. The stuff that actually wears these machines down is not a single storm, it is the constant exposure. UV baking the plastics and fading the shell. Standing water and grass clippings sitting on the charging contacts. Sap, pollen, and bird droppings landing on the sensors. A cover does not stop any one dramatic event, it just cuts down the abuse the machine takes every single day it sits parked.
Install took about the length of this video and required no drilling into anything permanent.
