Landa has engineered a totally new gasoline-powered hot water pressure washer that does not need a battery as the electrical power needed to run the engine and burner is supplied by a high-output alternator on the engine. The two models of the self-contained, super-compact, SUV pressure washer features 6 and 7 HP Robin-Subaru engines that are coupled with Landa's proprietary Super-Duty Regulator to produce a constant supply of 12V DC power for the diesel-fired burner used to heat the water.
