After replacing the air filter element, and regardless of the design flaw, the pressure washer has worked well, with steady pressure and a long enough hose to cover a good-sized area without moving the washer.

Really nice little power washer, but has some design flaws.

The first is a design flaw.

This power washer has a Magor Design Flaw

This all could have been avoided if the manufacturer had put a (clean) air filter element in the sealed plastic bag with the manuals (or just not soaked the unit in oil before shipping).There is also what I consider a design flaw.

The only design flaw I can see is the brush skirt.

but I couldn't due to a design flaw that I hope SIMPSON fixes.

I've had the MSH3125-S long enough to put about five hours on it, and I've used it on wood decking, stone walkways, painted steel, painted wood siding, painted steel siding, plastic window trim, and concrete

My Father bought s $100 one from Home Depot and it leaked immediately

Works as it should.

Simpson will send new part as soon as available (6-8

I use it to wash vehicles, decks, vinyl siding and concrete so far and the variety of nozzles and everything works as it should.

Disappointing as they are responsible for the misleading documentation).

Highly disappointed as it was shipped broken, took forever to get a replacement part, and it failed with the replacement part.

I took some time to clean it and make sure that it should work as it's supposed to.
