⇨ RELATED: gab.com/leafblowerreview Another important consideration is the type of leaves that need to be vacuumed. If you have a lot of wet leaves, you will need a leaf vacuum mulcher that is designed for wet leaves. On the other hand, if you have mostly dry leaves, then you can get away with a less powerful vacuum mulcher. Whichever type of leaf vacuum mulcher you choose, make sure it has a large capacity, so you don't have to empty it after each use.
