A truckmount carpet cleaner is a carpet and upholstery cleaning machine that is mounted to the floor of a van or trailer. Thecleaning method is hot water extraction. The carpet cleaning company would park the van near the customer's premises, connect the vacuum hose and solution line hose into the carpet cleaning machine, bring the hoses into the building, connect a carpet cleaning wand to the end of the hoses and begin the process of cleaning the carpets and/or rugs.
Main components of a truckmount
A petrol or diesel fueled engine powers a high pressure pump and vacuum blower by direct drive. The engine will generally have a starter motor fitted alone with a pull starter and an alternator that charges the battery and supplies 12 volt DC current to all the electrical components. An on demand electrical fuel pump is bolted to the fuel tank or the machine and supplies the carburetor or injectors on the engine with a fuel tank that is normally fitted to the chassis of the van to supply the fuel pump.
The vacuum blower lifts the dirty water from the carpet.
The high pressure water pump pumps heated water and chemical onto the carpet.
A heat exchanger or a water heater are fitted to the machine to heat the water up through the exhaust manifold system. Instead of a heat exchanger, some machines have a thermostat-controlled boiler that runs on liquefied petroleum gas (LPG).
A chemical injection system is in place that injects carpet cleaning chemical into the solution line on the low pressure or high pressure side, depending upon the model of the machine.
Most machines have a mixer tank/water box which is a holding tank to store water for the high pressure pump on demand.
Some machines have a magnetic water softener fitted to prevent buildup of minerals to protect the plumbing components. Some systems in America fit a deionizer to the plumbing to purify the water in order to protect the plumbing components and to give greater cleaning effect.
A waste tank, fitted to the floor of the van, holds dirty water picked up by the suction hose powered by the vacuum blower.
A Vacuum hose connects to the carpet cleaning wand, delivering the dirty water to the waste tank, and a solution hose that pumps high pressure water and chemical from the high pressure system to the carpet cleaning wand.
Cleaning tools connect to the vacuum and solution hose. Cleaning attachments such as upholstery tools for upholstery cleaning, and power heads and rotary tools for carpet, can also be used to further increase productivity and enhanced results on certain carpet types and soil conditions. The attachments to the machine are also an important factor in delivering the right amount of solution and also the extraction of the solution. A well equipped operator will often have a large percentage of the cost of the machine invested in accessories, in order to achieve optimum results.
A main water tank is often fitted to the floor of the van. It holds fresh water, supplying water directly to the high pressure pump or the mixer tank. When such a water tank is installed, an on-demand supply pump is bolted to the main water tank, supplying water to the mixer tank or high pressure pump.
Where limited space is available, and a fresh water tank cannot be fitted, the machine will still retain its demand tank, but it will be fed from an outdoor "garden" water tap via a separate supply hose reel. This, of course, requires that the property has an external cold water tap, which can be hard to find on some commercial sites. However, by carrying a range of different fittings, a tap key (for taps that have their handle removed to avoid unwanted water usage), and enough hose on the reel, the cleaner will usually be able to handle this situation.
