A truck mounted carpet cleaning unit is mounted on the floor of a van or a truck. The method that is used when using such a unit is hot water extraction, and generally it is possible to use a stronger motor with a setup such as this, thus providing more suction when sucking up the water from the carpet.
Hot water extraction is a very effective way to clean carpets, because as the hot water is applied to the carpet with a cleaning solution, it penetrates and loosens dirt and grime. Then when the apparatus retrieves the water via the suction, the dirt and grime is sucked out of the carpet into the container of the apparatus.
Typically, the truck or van is parked nearby to the building or home where the carpet is being cleaned, and a long hose connects to the actual cleaner device that is being used on the carpet. A carpet cleaning wand is usually connected to the end of the hose as the instrument that is actually used to apply the water and cleaning solution, and then to extract the dirty water back into the truck into a holding tank.
Heat is transferred to the water via a heat exchanger as the water passes through it in the truck. The heated water helps to loosen the dirt, grit, and grime from the water as it is passed into the carpet. The horsepower of the unit can be anywhere from 16 to 60 horsepower, depending upon the size of the unit.
The biggest advantage of a truck mounted system is the convenience for the user, even though the initial cost is anywhere from $10,000 $35,000. It is a convenient method because it is very efficient with this method as opposed to lugging a portable unit around the house as cleaning occurs.
