Simpson Professional 4200 PSI (Gas - Cold Water) Aluminum Frame Pressure Washer w/ Honda Engine & CAT Pump

This is a great deal for a really high quality pressure washer. You cant beat this combo of Honda and Cat. This thing comes with everything you need. It is basically fully assembled right out of the box. All I had to do was put the handle on it, put oil in the motor (supplied), add gasoline and I was done. It started on the first pull.

This thing has a crazy amount of power. I was skeptical about the pressure regulation on the wand but it turned out to be one of the most convenient features. The soap suction tube works great also. The aluminum frame is a nice feature as well.

Overall I am very happy with the purchase I believe this pressure washer will last me a VERY long time. This has ample power to take care of anything around the house/ranch. It makes the pressure washers at Lowes and Home Depot look like toys.

Don't waste your money on this unit because it will not live up to your expectations. If you read the original review then you already know about the initial smaller problems like malfunctioning trigger gun, busted vent cap, etc. Now the problems have escalated to a new level with the cat pump leaking from the brass housing that contains the plungers.

Very frustrated with purchase! Originally I was told from my merchant (P.W.D.) to take unit to authorized repair center. I did, but once unit was delivered with est. turnaround looking between 1.5 - 2 months I called P.W.D.. They then said that since it was now at a repair center that there wasn't any resolution other than for me to wait. What? They instructed me to upon my first call. There response was they didn't have record of the first call. Wow, so I'm stuck. I regret the purchase so bad! Best advice I can give: Buy your unit from a merchant that is within a reasonable driving distance.

If you want enough power and volume of water to do about any cleaning job, this would be one to check out. I use mine for Business, I have two of them, run them every day ( no weekends ).

The Honda engine has brute power and the triple stage Cat pump kicks out 4.5 gal per minute. Water volume is every bit as important as pressure in most cleaning jobs. This unit comes with a wand that has a variable pressure front grip adjustment. If you are cleaning your car and don't want to blow the stripes off of it, crank down the pressure, you still have plenty of volume to safely use.

I use a 20 inch surface cleaner at full power on concrete with great results. Starts easy, good run time on a tank of gas. Not really a machine for a beginner, use the correct wand tip for the job, (it comes with 4 different ones) this thing has enough power to blow things apart if not properly used. Also works well with extension wands up to 24 feet.

Awesomeness, hope she runs forever. Bought the General Pump power nozzle, cleaning the s... out of everything.

If you have the money, this is the best! You have to be a little careful. It will take paint off very quickly. It blew the stickers right off my UTV and tractor. There is a dial to turn it up or down.

When power washing our front door water came through the seals and got all over the house.

This will save you time and effort, but again be careful, it's got a lot of power compared to lesser washers.

I wear ear protection while using this product. It is loud.

Powerful and easy to use. Best Power Washer I have ever used. Actually performs twice as fast as my previous washer.

Received the Simpson pressure washer, by freight carrier, with no damage. Took all of about 10 minutes to assemble, filled crankcase with oil (supplied with the unit) and filled the gas tank.

Quality of the unit is excellent. Very well built, and just a bit on the heavy side. But, this is a professional pressure washer. As soon as you crank up this baby, and pull the trigger for the first time you quickly realize that this isn't like any pressure washers you may have purchased from your home improvement store.

Very powerful spray pressure. The adjustable pressure control on the handle is very handy feature. I started out washing concrete at high pressure, and could simply turn the pressure control down to low to power wash the siding on the house.

I also purchased the Simpson surface cleaner device for this unit and wow! Amazing combination to quickly make concrete look like new. This Simpson power washer will reduce my power washing time tremendously! Everyone will want to exercise caution with this much pressure. You could quickly do damage to practically any surface if you are not careful. Remember the pressure is adjustable with the pressure control knob on the spray wand and the speed of the engine.


I am Very happy with this pressure washer. With the Honda engine and the Cat pump this will likely be the last pressure washer I have to purchase. I bought this 4200psi Simpson pressure washer to replace a 12 year old Troy-bilt 2550psi pressure washer. I am not a contractor.

Wow this thing has a ridiculous amount of power. I have an excavating company and I used it to clean the mud from the tracks of the skid loaders and excavator.

So fast and powerful. I'm a big guy and I was impressed when I pulled the trigger it pushed my arm back..haha.

Packing was excellent!!

This machine is just awesome - what used to take days now takes hours. I'm really happy with it. It was easy to set-up and get started cleaning without too much time and with no trouble.

More details...

The Honda engine seems to take a long time to warm-up but I assume it's because it's a big engine. It's awfully rough when warming-up, too, and the whole unit shakes quite violently. When it finally gets going, it's smooth and there's plenty of power.

The ability to adjust PSI via the wand is a must. At full PSI, it's difficult to manage changing hands/arms, which is necessary regularly. And, you can easily switch from cleaning wood to concrete by just turning the dial. It's a great feature. I'm not sure what I'll do when it breaks.

The hose is heavy and somewhat inflexible but that goes with its 4500 PSI rating. I bought an extra hose, too, for 100 ft total and it's heavy dragging it all around, not to mention how much more weight it adds to the unit when moving it all around and storing it.

I don't know what a turbo nozzle is not standard issue - I got one of those, too, and it's unbelievable.

I'm running out of things to clean, now.

I purchased this washer to clean my house and farm equipment. It has done a great job. I have washed the house, driveway, mower, truck and trailer. I am very impressed with the performance of this machine. I would recommend it to anyone needing a pressure washer.

Pressure washer wand started leaking badly within two hours of very first use. Need to send back, but also need the machine!

Overall, the pressure washer has good power, but it's too early to tell about the overall quality. Very disappointed that I have to deal with the wand situation.
