ABSTRACT:
A safety lock mechanism for a cleaning wand. A three position slide switch alternately engages a pivotal trigger and/or a pivotal door on the end of the wand handle opposite the cleaning head. In the first position, the trigger is locked and the door openable. In the second position, the trigger and door are both locked. In the third position, the handle door is locked but the trigger is operable. Controlled engagement of the trigger and/or door with the slide switch prohibits unwanted loss or discharge of cleaning fluid.
