This gasoline driven power tool is most appropriate for folks with more than ½ acre of lawn that gets covered with leaves each year. The machine sucks up leaves and small branches, shreds them and deposits them into a bag that is easily emptied when full. In short the self-propelled shredder vacuum will do the raking job quickly and simultaneously give you a nice pile of finely shredded organic material to use as mulch or to place in a compost pile. Most models do have a small chipper hopper attached that can handle small branches, up to about 2 inches. These are big machines and really are only valuable in the fall. The rest of the time they need storage space in the garage.
