AR390SS–2000 PSI/1.4 GPM - Powerful-Durable-Reliable. AR Blue Clean power washers have 50 years of pump building experience through the Annovi Reverberi brand! The 390SS is an updated, upgraded version of AR Blue Clean’s popular 390 model. The 390SS model generates an amazing 2000 PSI, up to 30 times as much pressure as a typical garden hose while reducing water consumption by over 80%. For normal high-pressure cleaning, attach the 25 degree (Green) nozzle tip for a “fan” spray or the 0 degree (Red) nozzle tip for a concentrated “pencil-point” high-pressure spray. For tough jobs, attach the Rotary/Turbo nozzle to increase the effective pressure spray up to 50%. The low pressure spray Soap (Black) nozzle tip automatically activates the detergent tank for easy detergent application with the spray gun. This power washer is much quieter, lighter and easier to use than a standard gasoline pressure washer and is certified by CSA International for safety. The AR Blue Clean 390SS-2000 PSI electric power washer is perfect for medium to heavy duty residential cleaning projects with superior results. Experience the AR difference; you will be glad you did!
