Review: Llegó en perfectas condiciones, muy fácil de poner a punto de funcionamiento. Excelente presión, limpieza profunda... Lo esperado... Hay que seguir las instrucciones de uso al pie de la letra y usar gafas de seguridad...
Review: I was initially reluctant to purchase a gas-powered pressure washer because I did not want to take on additional engine maintenance. However, after reading several reviews and watching instructional videos, I learned that to achieve a consistent high operating pressure, not just peak pressure, it is ideal to use a reliable internal combustion engine to power the pump. I compared several brands and ultimately chose the Simpson 3400 psi model because it is made in the United States and provides the pressure level I need to remove mold and algae from my pool cage’s aluminum frame, as well as to clean my deck, driveway, and sidewalks more efficiently. So far, I am very satisfied with the performance. The pressure is significantly higher than that of my two previous electric washers, and the unit appears to operate reliably. The noise level bothered me at first, but I quickly adjusted. All components appear to be of good quality, at least as they look when new. In addition to the overall build quality, the larger wheels make it much easier to move the washer around, especially on grass. In summary, I am very pleased with this purchase, and based on my experience so far, I highly recommend the Simpson 3400 psi model for home use.
