Work (HP)
”
Definition:
There is one more factor to remember when buying power washers, which are sometimes equally as important as pressure and water flow. That’s work. The unit for work is HP (horsepower), which determines how much power the machine has to clean the surface. Typically, the more horsepower a machine has will allow for higher pressures, volumes, or a combination of both. Larger engines are more powerful and, therefore more capable of finishing the job quickly.
