Tucker® Aluminum Pole 40' Dual Hose
The ADH (Aluminum Dual Hose) method consist of a dual hose line with 2 independent water lines and connections. One line flows into the base of the gooseneck like described in the ASH method and the other comes outside of the top of the pole and enters an over the top fan jet sprayer. The water flows out the flow screws in the brush as well as out of the over the top fan sprayer. This method is often chosen for cleaning solar panels because you are able to put a large amount of spot free water on the panels and clean very quickly.
