I live in a 5th floor of a building that doesn't have strong water pressure. I remember that many years ago a cleaning group was going to pressure-wash the exterior of the building, but couldn't because, supposedly, the water pressure wasn't strong enough. I wasn't there at the moment; a neighbor told me this.
So yesterday I saw a 1,450 PSI electric pressure washer for around $80, and I was considering buying one to clean the rooftop. But now I'm reconsidering.
So, my question is, does low water pressure actually affect the functionality of a pressure washer?
What my neighbor told never made sense to me. From my understanding, the purpose of a pressure washer is to work with low water pressure.
