The tank was wrecked so what good can come from this? We can salvage the handle and use it on a Scooba tank with a wrecked handle but a good Solution Valve. First step is to remove the two screws on the bottom of the tank

Next, use a flat blade screwdriver to pry the RIGHT side of the tank handle so the little tab can be cleared and the handle can swing forward slightly. Then pry on the LEFT side and the handle can be rolled out.

Here is the handle looking from the front of the tank. Notice the difference in the lengths of the right and left tabs that lock into the tank.
