Karcher rotating nozzles, such as the Karcher Rotary Turbo Pressure Washer Nozzle, Size #100, 4350PSI (9.302-446.0) combine the deep cleaning penetration of a solid, 0° pencil jet nozzle with the large coverage of a fan jet nozzle. By spinning at 4000 RPM, the rotating nozzle delivers 50% more cleaning impact than conventional fan jet nozzles. Each of Karcher’s rotating nozzles are made of long-lasting ceramic and have very few moving parts for low maintenance.
