There are many different types of cleaning companies in which require a industrial pressure washer and a large water supply. These businesses tend to be mobile as they focus on cleaning wheelie bins, driveways and patios, washing down carparks, supermarket trolley bays, heavy equipment, external buildings and also washing cars. This is where a pressure washer water bowser comes into action as it can be easily towed on the public highway (if trailer is highway spec) giving companies a mobile solution to reaching their customers without the need for a water supply as they will have their own water supply from the water bowser and industrial pressure washer in which can also dispense detergent for a deeper clean.
