OVERWETTING
Overwetting is annoying to all concerned, and may leave a bad impression of the
cleaning process used.
THESE ARE SEVERAL AREAS THAT WILL CAUSE OVERWETTING
1. Too few vacuum strokes or improper saw-tooth vacuum strokes as
shown in the following illustration.
2. Obstructed, cut or kinked hoses.
3. Vacuum tank drain valve left partially open.
4. Clogged vacuum blower filter or vacuum tank lid not sealing properly.
5. Cleaning a heavily foam-saturated carpet without defoamer.
(We recommend crystal type.)
