The second category of steam cleaner is the truck mount as has been referred to above.  This is a powerful piece of equipment that can cost 10 to 20 times as much as portable equipment.  The equipment and all its attachments fill the inside of an average sized van.  

It is best viewed as a cleaning plant.  The technician runs a long hose from the truck into the house and never has to add or dump water during the job.  

Because the equipment is bolted to the truck, larger vacuum motors and spray pumps can be used delivering much more power at the point of contact with the carpet.  As a result of the more powerful vacuum action the carpet dries faster than with portable equipment.  

They also heat the water well above the level of the average home water heater boosting the cleaning power of the solution.  As a result, you often don’t need to vacuum, spot or scrub before you steam clean it.  A skilled carpet cleaner canget your carpets just as clean with a portable unit, but the job can take longer and the carpets will take longer to dry.

Over-Wetting

A problem that has occurred with shampooing and with steam cleaning is Over-Wetting.   Over-wetting can cause odors, shrinkage and mildew.  Some carpets can take up to 2 days to dry without being over-wet if the ventilation is poor or for a variety of other legitimate reasons like a thick pile.  This does not usually cause a problem, and if it does, in almost all cases it can be easily corrected.

Over-wetting is when excess solution is left in the carpet that should have been removed.  It is caused by poor or faulty equipment, laziness on the part of the cleaner, inexperience or poor training.  There really is no excuse for over-wetting.  Professionals don’t have this problem.

Dry Cleaning

Over-wetting is a rare occurrence.  But because of the fear of over-wetting, various forms of dry cleaning became popular during the 1990’s.  There are many different dry cleaning methods available.  Some use a powder, some use a carbonated liquid that dries in about 1½ hours, etc.

Dry cleaning is very safe, but it has not achieved the cleaning results of other methods and tends to leave some residue in the carpet.

Summary

As a final important note, no method is a substitute for a skilled technician.  Any method misapplied will not achieve the best results.  On the other hand, a skilled technician can get a good result with a bucket and a brush if that’s all he had.
