Apparatus is described which is adapted to analyze various operating conditions and characteristics of steam cleaners and pressure washer (e.g., of the type which heats water and forces it out of a nozzle under pressure). The test apparatus includes means for testing and analyzing operating characteristics and parameters such as inlet and outlet water temperature, water pump head pressure, coil outlet pressure, fuel pressure, water flow rate, voltage and electrical current draw, stack temperature, and hydrocarbon emissions. The test apparatus is useful in servicing pressure washers and in comparing the operation of one pressure washer to another pressure washer. The test apparatus is also very useful in detecting possible safety hazards existing in steam cleaners and pressure washer.
