It would seem like an ideal solution in that it ought to make cleaning up the yard quicker, but bag capacities are limited. BLACK+DECKER leaf vacuums have a very efficient mulching mechanism, which means you can get way more in there than would otherwise be the case, but the bag still requires fairly regular emptying. To be at its most efficient, it also needs fully dry leaves. We’d say a collecting bag is a good solution for a modestly sized yard, but in larger areas you’ll probably get the job done more quickly with a blower.
