Not the way it should be done. High pressure can genuinely damage siding, stucco, painted surfaces, and older wood -- which is why a proper job uses a low-pressure soft wash with cleaning solutions on those materials instead of blasting them with high pressure.
Concrete, asphalt, and paver driveways can handle higher pressure because the material is much more durable than painted wood or stucco.
Vinyl, wood, and fiber cement siding, along with painted surfaces, all hold up better under a soft wash -- the cleaning solution does the work that pressure would otherwise have to do.
