KARCHER'S new line of compact, gasoline-powered cold-water pressure washers come in three models, powered by Honda engines. All three offer the cleaning power of up to 3.6 gallons per minute and 4,000 PSI. (Two of the units weigh less than 100 lbs.) Precision-welded chassis are protected by an epoxy, powder-coat wrinkle paint, and come with pneumatic tires for easy maneuvering in all terrain.
