Abstract: A self-contained cleaning system using a truck mounted cleaning unit. The cleaning unit has a dual water tank system which is used to recirculate water through a propane hot water unit until the desired water temperature is obtained. The dual water tanks also permit the operator to bring his own supply of water to the job site. A dual pressure water unloading system allows quick switching from high to low water pressures while quick disconnects on the unloading system permit rapid removal for maintenance and/or replacement of the dual water pressure regulators used. The cleaning system is totally self-contained and may be operated without using the utilities of the customer.
