PROBLEM - Over Wetting

CAUSE: Over wetting of carpet is the cause of most cleaning related problems. It can be caused from the following items;

• Blockage in vacuum systems
• Leaks, cracks, collapsed vacuum hoses.
• Damage to the wand that causes restriction of air-flow
• Waste tank seals missing or damaged
• Vacuum filters clogged
• Improper speed or RPM settings (truck mounted systems)
• Worn vacuum pumps and motors
• Over-application of solutions, due to pressure settings too high and/or improperly sized jets in the cleaning wand.
• Over-applying shampoo solutions. Note: Shampoo solutions should have good foamin qualities to help avoid over-wetting
• Improper cleaning technique. Operator over applying solutions and not taking proper vacuum strokes.

SOLUTION:

• Reduce pressure setting of pump
• Insure vacuum system is operating properly
• Re-extraction of excess moisture
• Employ proper drying technique - use a Turbo dryer whenever possible.

The following is a listing of principals that will effect the drying process:

• Proper air circulation is necessary for quick drying
• As air becomes saturated with moisture drying slows down
• Warm air will hold more moisture than cold air
• Fans are dehumidifiers will decrease drying time
• Air conditioning units act as dehumidifiers.
