Our tanks have been designed to cope with the reality of the field. We don't have the biggest capacities, because we know very well that technicians don't fill them completely when they are bigger to be able to transport the machine with ease. We have therefore opted for reasonable volumes of water and soap. In addition, the tanks are often filled in an environment where contaminants can easily seep into the tanks. For example, pieces of grass or debris can enter the water tank when it is filled with a garden hose in the customer's yard. To ensure the durability of our equipment, we have added filters.
