I actually received one of these 1300 psi electric pressure washers for Christmas a couple of years ago. I think mine came from Wal-Mart. Don't rely on it to remove any road film off of your car, but it will work in a pinch to remove caked on mud, and other debris. I have used it more to sweep my driveway and front sidewalk than for washing the car. I find it is easier and faster to just get the bucket and soap, and wash by hand. It takes some time to get it out, plug it in, hook it up to the hose, etc. I am already halfway done washing the car by hand in that amount of time. Like said before, it does have some practical uses around the house though, I would rather search for a higher powered gas pressure washer used instead.
