This is a good point about choosing the cleaning method based on the surface. Brick and concrete may look tough, but they can react very differently to pressure, especially if the brick or mortar is older. Using too much pressure can actually damage the surface rather than improve it.
I've found that a careful test spot and the right nozzle/pressure make a big difference before starting a larger job. For concrete, a proper pressure washing approach can do a great job removing built-up dirt and grime, while more delicate masonry often needs a gentler method.
Overall, the advice about checking experience, cleaning methods, and reviews is spot on. A good cleaner should be focused on restoring the surface without causing unnecessary damage.
