Tons of Power!

Bought this to clean a 2 story house with very high peaks. The machine did great and no problem getting the stream of water to the peaks. It started on the second pull after getting it unboxed, assembled, and the oil in and started on the first pull each time while starting and stopping it while pressing washing the house. Very glad I pulled the trigger to buy it; it FAR out performs my previous 2GPM 2200PSI machine..night a day between the two. So far it's a great machine!

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!

O más natural para una reseña: I’ve had this pressure washer for 10 years, and it has worked great. I just bought another one because it’s honestly that good. Highly recommended!
