The Snow Joe Ultra SJ620 is light. This allows you to clear snow in no time. But this is really best for powdery snow even if they are 10 inches thick. It can also clear a path at a width of 18 inches.
Having an efficient yard tool is important, but it should also be complemented with ergonomic design to make practical work. The Toro 51621 Ultraplus Leaf Blower Vac is certainly both efficient and comfortable.
