Spring Cleanings

Washer itself works as advertised but two problems found with mine. #1 the white spray nozzle was poorly cut causing an uneven force of water. It does two stripes of cleaning rather than one. #2 the gas engine is low enough in the carriage the grass underneath burned out from the heat.

Mega Shot

Easy to crank and operate, has plenty of power, so far i have no complaints, except it will kill the grass I suppose due to the heat from the engine, otherwise I like it as good or better than any I have owned.

Simpson pressure washer 3400 psi.

Machine is great. Easy starting and lots of spray power. Only drawbacks are the plastic spray hose Which lacks flexibility and ease of handling and the stubby handle making it difficult to move from place to place without tripping over the frame.

Truth in marketing award winner

I use mine for home and yard cleaning (works great on leaves in the fall) and helped a few friends and family with their driveways and patios. The reliability and easy start descriptions are not overstated. Mine is 7 this year and it always starts on the first pull. It always runs until I shut it off. When I'm done cleaning I use the gas line shut off valve to stop it and service it according to the manual. Same with the pump. Same with the hoses.

Missing parts

I received the product missing the thermal pressure relief valve. Having used a pressure washer before I couldn't understand why a large amount of water was leaking from the bottom of the pump but it still spayed. After doing some research I found that is was leaking from a threaded hole on the bottom of the pump. I thought it was just missing a plug of some kind. After finding a scymatic of the pump it showed the relief valve was missing from the factory. Obviously someone in quality control is not doing the job!

Simpson quality speaks volumes!

There are lots of pressure washers to choose from. Some people choose by PSI and GPM. I like to look at what components are being used to deliver those numbers. In this pressure washer you have a Kohler engine with commercial features like a cast iron cylinder liner and roller bearings. You get an OEM pump for reliability and pneumatic tires to roll more easily wherever you have to take your washer. And best of all, it's made in the USA! What else could you ask for? I'm pretty careful with my machine maintenance and I know I'll have this washer for a long time. I've already used it on a couple of jobs around the house and I am very satisfied.

The good and no so

[This review was collected as part of a promotion.] Wand is A short 15 1/4 ", no .25 degree [green] nozzle tip. .On/Off ignition switch in the wrong place with the unprotected wire exposed. Like the 6.5 HP engine , 3400 pump, compact size, long sturdy Hose. And Bang for the buck. Hose to wand connect is very hard to use due to being so close to handle grip. Needs a quick connect on that hose end. Got this as A gift on sale. Would be A ten plus machine if not assembled [ in the USA] from extra parts.

oil leak

After using it for appx 2 weeks, it developed an oil leak between the pump and motor. Called the manufacture and I was directed to a local small engine repair shop with it under full warranty, and they still have not even looked at it yet. Don't know when I'll get it back. ugh lost a couple jobs because of the inconvenience.
