For years I used a gas powered pressure washer, but if it went unused for a while, the carburetor would be gummed up and need to be overhauled. This electric unit has all the power I need, and it's maintenance-free, not to mention much easier to set up, start, and put away afterwards.
Ordered this unit online and it was very easy to put together with just a Philips screw driver. The build seems rugged enough and the cord is sufficiently long so you don't need to move the unit too much. It's compact and moves easily for storage. The only negative I have is that the power cord is rather rigid so if the temperature is below 70F it has a mind of its own.
