I don’t have this exact model but I own a similar electric snow shovel. I was surprised how well it cleared my 16’x10’ deck of the 5 or 6 inches of snow we had this past week. However, keep in mind that the snow is thrown straight ahead of you and 10’ up in the air. Consequently you need to make sure that you shovel in a direction that you don’t mind having a snow bank build up.
I made the mistake of directing the snow right onto the steps I had cleared off first.
