Answer: In some cases
Explanation: Yes, pressure washing can damage concrete if not done properly. Using extremely high pressure or a concentrated nozzle can cause surface etching, pitting, or even break off pieces of concrete. This is especially true for older or already damaged concrete surfaces. To avoid damage, use a pressure setting below 3,000 PSI with a wide-angle nozzle, and maintain a consistent distance from the surface. It's best to start at a lower pressure and adjust as needed to safely clean the concrete without causing harm.

Explanation: Pressure washers can damage concrete. Some things to consider before pressure washing concrete are the quality of the concrete, age, how the pressure washer is used and frequency of cleaning. Concrete is rated for a certain weight per square foot/inch etc. exceedingly high pressures can do a lot of damage and even remove that skim coat on the top of the concrete surface exposing the aggregate and often unsealed/unprotected layer of concrete below it. Even when professionals use rotary surface cleaners damage can still be done which is why it's important to take the above into consideration and adjust your spray nozzles accordingly.
