OVERWETTING
Overwetting is an annoyance to all concerned. Extended drying times will leave the
customer with a negative impression of both the cleaning company and the process used.
There are several factors that will cause overwetting:
1. Too few vacuum strokes.
2. Clogged vacuum blower lter or Recovery Tank lid not sealing properly.
3. Recovery Tank drain valve left partially open.
4. Obstructed, cut or kinked vacuum hoses.
5. Obstructed vacuum hoses while cleaning a heavily foam-saturated carpet (it is
recommended to use a crystal type defoamer distributed evenly over the carpet).
STREAKING
Streaks in the carpet can appear in both clean or dirty areas and normally appear in
heavily soiled, light colored carpets.
Possible reasons of streaking may include:
1. Clogged or improperly angled spray nozzles.
2. Spray nozzles that overlap, concentrating the solution.
3. A partially clogged vacuum head.
4. Inconsistent solution temperature.
