What does really matter for you when it comes to buying a pressure washer? Obviously, what works for some people is less likely to work for everyone else. At this point, you need to determine whether you want silence or speed. You cannot get both of them. For instance, most units release around 85dBA or more. More noise might demand hearing protection. Electric models are less noisy though. But then, they are slower. What feels more convenient for you? Take a look at http://www.washwisely.com/electric-pressure-washers/ and research your options. A few reviews can open plenty of doors, so try to take your time and avoid rushing for a good choice.
