The way a cordless leaf vacuum works is pretty similar to that of a normal vacuum cleaner. The leaves are soaked up, eventually chopped, and then fall into the tools collection bag. After the bag is full, it needs to be emptied manually. In contrast, the functionality of a leaf blower is more similar to that of a rake. Even though the cordless blower is motorized, the leaves are first directed to a central location, from which they have to be removed manually afterwards.
