Excellent for gum removal on concrete!

We love our Simpson machine! Throughout the years I e worked with several models and they have never let me down! I love the fact that the can remove the old dried up gum from the school grounds without damaging the concrete! The size of the machine makes them extremely portable and easy to move too! Simpson is the brand for us!

What an amazing working machine

I just bought and used it in a family friend house. The power is amazing, and the easyness to set it up and work is instantly. I am very happy with the choice and the options to do the work, the manuals, instructions and videos on how to use very helpful.
