Electric pressure washers don't have enough volume to do much other than wash your car or rv then at that they are slow. Try to wash out a cattle trailer or mud or dirt off of deck and an electric is worthless. A gas powered Troybilt or similar has way more volume and higher pressure. As far a paint sprayers go I had a Wagner Paint Crew. I used it about six times over a two year period painting the I beams for several barns I was building. Then it broke. The plastic piece that broke was not replaceable so I had to buy a new sprayer. I bought a Titan unit from Sherwin Williams. It wasn't cheap but you can get parts for it and so far it hasn't broke. I have painted two barns, several pipe fences and more I beams. Only complaint about any paint sprayer is that it takes several gallons of paint thinner to clean it when you are done so this discourages you from using it for small jobs.
