My previous pressure washer, sporadically used, sat outside under the eaves for a few months. Upon trying to use it, it was stone dead. I diagnosed a GFCI failure, replaced it, and the unit powered up but there was only unpressureized output. At this point I decided to replace it.
Research into reasonably-affordable pressure washers led me to this unit. I was surprised to find that Westinghouse made units such as this. In the days before computers, my father worked for Westinghouse designing blades for the huge steam turbines that power electric generation plants. I pictured the company as only dealing with huge industrial machines, so this was quite unexpected.
The unit came well packaged in a very substantial carton. Assembly was simple, mostly entailing sliding various plastic pieces together. The instructions were somewhat on the skimpy side for someone unfamiliar with the unit; I would have appreciated a little more detail. I found a video online showing the process, so that plus the instructions was fine. A couple of the pieces were a bit balky to install, so a spritz of silicon spray easily solved the issue.
The unit is delightfully small, even with the stabilizing outrigger wheels. I've used it a couple times, first to blast some moss or algae mysteriously growing on my aluminum shake roof, and then to rinse off some large windows. I haven't tried the soap blending facility yet; that would presumably do a better job on the winows. And I blasted a surprising amount of dirt from my sliding patio door tracks.
The manual didn't identify the various colored nozzles. They had raised plastic numbers that these aging eyes couldn't discern. I took a picture and enlarged it, enabling me to learn the values. I wrote R G and Y in the manual next to the listed angle values. Then I noticed that the warranty request card had the values listed. Oh well.
Both the electrical cord and the output hose are impressively long.
I'm very happy with the Westinghouse unit. A couple minor gripes if I might:
1. The output hose is rather platic like and kinks easily. My old unit had a rubber hose and if by some miracle the connections are identical, I'll replace the Westinghouse hose.
2. They apparently expect users to unscrew the 14" lance from the trigger unit to store in the two receptacles on the machine's side. As one unit, it isn't well supported in the much shorter vertical space available. I don't like that.
3. There's no drain on the soap tank, unlike my old unit. When I use that feature, I'll have to either invert the machine or purchase a turkey baster.
These are not big complaints. Based on my early experiences with the 3500, I can recommend it to anyone needing a non-nuclear household pressure washer.
