This MEA asks the students to decide on a pressure cleaning machine that will provide the Sidewalks and Roof Cleaning Services Incorporated company with the best value for their money. Students are asked to rank order of pressure cleaning machines in term of consumer rating, gallons per minute (GPS), pounds per square inch (PSI), cleaning units (CU), whether it is gasoline or electric operated, price, and amount of time the pressure cleaner takes to clean 10 square feet of surface area. Students must provide a "Best Value" pressure cleaner to the company owner and explain how they arrived at their solution.
