Carpet cleaning equipment does not just include the heavy machines that help you get the job done; it includes everything in the carpet cleaning industry, commercially and residentially. This includes equipment that is portable like a steam carpet cleaner or something that is not so easy to move around like truck mounted cleaning equipment. Portable needless to say is more relevant to home usage while truck mounted gear is suited more for industrial sized jobs. This equipment is too massive and resides in a truck or van or some other mobile transport.
Truck mounted carpet cleaning equipment has long hoses that can penetrate deep into a business from the truck that houses the cleaning machine. The truck itself acts like a generator to power the equipment. It's a heavy duty no joke type of equipment that can be very dangerous to use for someone who does not know what they are doing as it uses pounds per square inch in water pressure to clean carpets and floors.
The residential equipment uses heat and water to break up the stains. It's a steam carpet cleaner of sorts. The brushes agitate the stain and then the cleaning machine blasts the carpet with hot water to break up the stain and the heat dries the carpet afterwards. It's not for heavy industrial use and is more appropriate for light stains associated with home spills. A downside of this type of equipment is that the heat is not sufficient to thoroughly dry the carpet so it may take a few days to dry. This can create mold issues.
With portable equipment it can still be heavy enough that it can take a truck or van to deliver it but is often self-propelled. This kind of portable carpet cleaning equipment is used exclusively in industrial settings, mostly by janitors or a professional carpet cleaning company.
