Setting a new standard in the pressure washer industry, the CAT 1800 PSI electric pressure washer is powered by a patented 5 piston pump, generating the highest water flow per PSI of any electric pressure washer. The high flow, high pressure performance ensures superior cleaning power. Our focus was to have the highest working water flow and working pressure to have the optimized impact force for the fastest, most effective clean. Other pressure washers on the market chase high pressure at the expense of water flow - leaving you with poor cleaning performance and long job times. An all metal gun assembly, real rubber hose and maintenance free motor ensures reliable performance throughout its effective life. The compact design with thoughtful organization features ensures set up, use and storage are easy. No questions asked we've got you covered. 2 years on the entire unit and accessories.
