My old Devillbis gas unit gave out so I decided to replace with an electric pressure washer. I got mine at Lowe's; I can't remember the name right now. It is 1800 psi. The comment regarding looking at amps vs psi is a bit off base. Basically, the more psi (pounds per square inch) you have, the more work per unit time you can accomplish. More psi requires more electical power (watts). Volts times amps equals watts, so on a fixed line voltage like 120 VAC, you need more amps to get more psi. There are a lot of other things to consider. It is possible that your 3600 psi pressure washer will peel the paint off the wall while trying to get the dirt off. More power isn't necessarily better.
What I found was a great idea was buying an accessory package with three or four extension wands and a broad selection of nozles. I was able to get extensions long enough to reach straight on all the way to the roof peak in my metal pole barn. I could get very good local pressure on the wall at 1800 PSI to strip off dust, cob webs, and bird stuff without damaging the paint or wooden surfaces.
I also like that the electric unit is much quieter and shuts off when you release the trigger. Since my barn has power, I didn't need to have a heavy duty extension cord, just enough hose to reach the job.
