Simple to use my little giant!

I had purchased the headshot 3100psi in September and it did such a great job my son decided he would buy one . Seeing how close to Christmas we are l gave him mine and I bought the next size up? It's amazing what 300 more psi can do! Both are great machines. If you need a pressure washer, you definitely should try a Simpson product!

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!
