There are two common types of wands--the variable pressure (or dual lance) wand and the straight through wand. The variable pressure wand allows the user to simply twist the handle on the wand and reduce the spray pressure. If the chemical injector is attached, the soap or chemical will automatically be injected into the water stream after the pump when the pressure is turned down. Simply turn the pressure back up and the soap injector stops drawing soap. In addition to the convenience, this is the best way to apply soap because it never passes through the pump. Many soaps and chemicals are harmful to a high-pressure pump.
