Many Hotsy gas-engine drive pressure washers are delivered to the customer with a dual lance wand, for ease of detergent application. These variable pressure wands, when used in conjunction with a
downstream detergent injector, controls the flow of power washer soap, merely by turning the handle. A dual lance wand uses two nozzles; one is a high pressure nozzle and the other is a soap nozzle, with a large orifice (opening). By turning the dual lance wand handle, it allows water to flow through both nozzles, thereby reducing the operating pressure (PSI) and simultaneously creating a venturi (vacuum) that begins the flow of pressure washing detergents.
If you would like to add a downstream detergent injector and variable pressure dual lance wand system to your power washer,
