Hey guys, Was wondering about the billy goat vacuums. I am looking at the KV model and the metal monster wide area vac. I know the kv has a leaf shredder but I don't know about the wide area vac. I have some yards this year that are a dread to clean up. One yard is a steep hillside and puts out 100 bags of leaves unmulched. Leaves were so thick that when we were blowing them they got into several piles as tall as my neck ( about 5 feet deep ) My question is: Does the kv vac with the leaf shredder better than the wide area vac?
