Works as advertised.

Used 3 times so far works as advertised. Siohon tube worked fine and Honda pulls once and starts. Package came with everything advertised. Machine is very balanced and i like the aluminum frame.

Cat pump Honda motor say no more

Reliable plenty of power will last for years my first one lasted 15 years and it still runs. Remember your pump is only as good as the water pressure that you have feeding it

Good pump action.

Looks well designed. Trouble getting started. Advice to KEEP pressure released while pulling cord to start would have helped. Found that advice elsewhere. Heart rate for us older folks at risk

Looks Great

Compact

I would like to see the handle about 18” way to low, the hose is so stiff I replaced it with a different one. It would be nice if they had a retractable hose reel. Packaging was not very good.

I did my homework and got the best for my needs

I paint houses, so needed a power washer that was powerful and reliable. The triplex piston type was the best one for my needs. My truck and horse trailer are always clean, as is my carport, house, concrete walks and water troughs.

Great Machine

I had only one problem during assembly, the holes in the handle bar did not line up with the holes in the handle.I had to drill a larger hole so I can fit the screw to match up with the holes.

Best Pressure Washer

I just bought a Simpson 3200 psi pressure washer. It is my 4th 3200 Simpson I have used. This is a quality product but the difference was this company gave me a much lower price along with free shipping. Hats off to You!

Hydraulic pump leaks oil

The hydraulic pump leaks oil badly, so the washer has no pressure. It's in for warranty repair at one of your local service providers. They told me yesterday that it will probably take a long time before I get it back. Pretty disappointed!

small but mighty and quiet and powerful

I was very impressed with the Simpson pressure washer. It was small and compact but did the job that it was intended for. The price was not bad for the quality that went into this machine. I would recommend this machine to my friends and family.
