If you have facebook.. join the Obsessed Garage forum. Because of them, I purchased the Sun Joe SPX4001 2030 PSI 1.76GPM. I then detached it from its base and wall mounted it. Purchased a 100ft hose and a wall reel and plumbed the water directly into the pressure washer. The attached pic is before I plumbed the water in from the pipe below.
With that said., this washer is fantastic for an electric. The price is dirt cheap at $150. Buy from Amazon.. you will not be disappointed.. IMO.. gas isn't the way to go if you want something for your car. It makes no sound once you let go of the trigger.
