Wands have a great effect on the end results of cleaning and drying. First, a wand with an efficient vacuum design does a much better job of extracting soils and solution. The result is a cleaner carpet, nearly dry to the touch, reducing total drying time. That is especially important on those overnight commercial jobs that need to be dry by the start of the next business day.
Equally important as full-flow design is heat delivery. Generally we think of the truckmount when discussing heat. Yet, the greatest heat loss is at the wand head. The more distance between the jet and the carpet, the greater the heat loss. That’s why the spray from a single jet wand is relatively cool by the time it reaches the carpet. The atomizing effect of jet spray releases a tremendous amount of heat to the atmosphere.
