Anyone can go to their favorite hardware store or big box store and purchase a pressure washer to clean everything around their home. Each year there are injuries from these powerful machines. Most people take them home, hook them up and away they go. They are unaware of the real pressure that comes out of the tips and that the tips sold with them are designed to clean hard surfaces. They also don't know that the way to reduce the pressure is to buy tips that have bigger orifices.
Before you go out and buy a pressure washing thinking you're going to clean the world, think of the bodily injury or the damage you can do to your home. In the end, it might be a lot cheaper to hire a professional who knows the machine they are using and takes time to go to national training and seminars to become well educated on the use of a machine that can produce damaging pressure.
"Consumer Reports no longer recommends pressure washers that come with
nozzles or adjustable wand tips that produce sprays of less than 15
degrees."
