The lightweight, compact JM-1000 Mini-Jet gives you 1500 psi of cleaning power, yet weighs just 23 lbs. Clear grease, sand, and ice from 1-1/2″ to 3″ lines. The pump and motor assembly are safely contained in a rugged metal diamond plate case that can handle abuse in the field. Water jets use a stream of high pressure water that hits the stoppage and flushes it away. The thrust of the nozzle drives the hose down the line and gives you wall to wall cleaning action. Pulse helps the hose slide around tight bends and farther down the line. This is what separates General’s Jet-Set from ordinary pressure washers. It breaks the initial tension between the surface of the hose and the walls of the pipe, increasing cleaning power. The JM-1000 Mini-Jet generates 1500 psi at 1.4 gpm, yet pulls only 13 amps. The pump and motor are enclosed in a metal housing and protected by a 3-wire Ground Fault Circuit Interrupter.
