I got tired of fussing with my gas powered Honda power washer and bought a corded electric Dewalt for about $250. It works just as well, way more convenient, and has a pulsing masonry tip that is amazing for getting the moss off of my patio bricks. 

 Mine is electric too. I used to borrow my parents gas one until about 6 years or so ago and bought an electric one. It's fine for all I need to do. 

 My neighbor's gas powered Honda is much more powerful than my electric.
