SIMPSON Pressure Washers ALH4240 Editorial Review
This pressure washer has various features according to its model, including an adjustable cat pump and chemical hose attachment, and a siphon tube that draws directly from the supplied container. A county water supply can handle the 4.0 GPM required by the pressure washer, and it recommends using a 10W30 motor oil for the engine and a 15W40 motor oil for the pump. Overall, this pressure washer is powerful and delivers clean results. However, some customers have reported negative experiences, including leaking handle and damaged frames, guns, and wheel kits during shipment. Some customers also experienced pump failures after a short time, and the machine being defective upon arrival. Customer service was reported as either helpful in some cases or horrible in others.
