A truck setup draws fewer leads compared to a trailer as it has less appeal and it is harder to notice.

A pressure washer trailer is a better option for small and growing pressure washing businesses than a truck because it requires little to no maintenance, uses no fuel, and it is cheaper.


  • It Is Not a Multi-Purpose Unit

A pressure washing trailer is only specialized in carrying a pressure washer and the pressure washing equipment and it cannot be used for other purposes.
