Harsh bristle controls the over-spray and never scratches the ground. 3 Jets Fast Cleaning: Our pressure flat surface cleaner is equipped with 3 high-speed rotating jets. These 3 spray nozzles are formed as a 25-degree design to provide faster and complete cleaning. Also, the nozzles have only 0.06'' diameter, making the water-intensive and ensuring a strong cleaning effect. Premium 24'' Surface Cleaner: The surface cleaner delivers a commercial level cleaning about an area of 24'' wide with its high working efficiency. Max. working pressure 4000PSI at 8.5GPM and Min. working pressure 800PSI at 2GPM. Note: If there are large rocks in the area you are cleaning, please clean them before using equipment; otherwise, the stones will damage the water outlet. NOTE: The high-pressure washer equipment connected to the surface cleaner shall not be less than 1000PSI. Higher pressure brings a cleaner washing effect. The nozzles are very small, which is particularly easy to block. As long as one is blocked, none of the three will work.
