We have a raised ranch and this year I am forced to do the roof by myself. My husband had shoulder surgery so I decided to try your model 500. I am only 5’2″ so I used our 8′ ladder to stand on being very careful. Needless to say it took me 1 hour to clear the north side of our house which is 32 ft long and I have to say it worked great. The snow I removed (24″in one day) has been sitting on the roof for 6 days and ice started to form on the edge so again I had to careful.
Thank you for a great product.
