I have two of these:

Definitely comparable to gas pressure washer, but it requires a 20A plug/extension cord. The built in cord is pretty long at 36' though.
There is a cheaper version that is apparently somewhat worse in performance but only requires at standard 15A outlet:

Haven't tried it though.
The 20A ones get used 1 week on/two weeks off so far for 5 years with no worries except oil changes (non-detergent SAE30, which is a bit unusual). If reach isn't an issue, I'd recommend this over the 15A version.
EDIT: if you do get one of those, you'll want to replace the stupid pneumatic tires that will always be flat when you want to use it with some solid ones. It has a 3/4" axle, not 1/2" or 1" which is a bit less common.
