Customer Reviews for Simpson Clean Machine by 3400 PSI at 2.5 GPM Cold Water Residential Gas Pressure Washer

I bought this pressure washer due to the price and high PSI. I am removing paint from concrete and needed a powerful PSI rather than the electric pressure washer at 1800 PSI I already have. This thing is a beast! I attached a picture as there is still some paint that is not coming off and I would need a commercial pressure washer to remove. I believe if I put more time into it, I would be able to remove most of the paint here. The entire backyard was red, so the red paint left is almost gone. I am very happy with this pressure washer!

This is our second SIMPSON CLEAN MACHINE 3400 PSI AT 2.5 GPM COLD WATER RESIDENTIAL GAS PRESSURE WASHER. It is powerful enough to do large homes, sidewalks, patios, etc. We change out the connectors to quick-connect because we like the ease of setting it up. You can get a quick-connect at Home Depot. The pressure washer is compact and easy to move around. It comes with a hose and tips for different applications. Ours came without a part, but the company sent it to us without question. The only thing we do not like about it is that the water hose attaches to the gun in front of your hand instead of behind and bellow. This makes it a bit awkward to handle.

The Simpson Clean Machine is a very impressive pressure washer. Using cold water, at 3400 PSI it can handle any job a homeowner might need to perform. A gas powered machine it uses on average 2.5 gallons of water per minute. Compared to other washers I've used, it is very easy to start, typically with a single pull and little effort. Included with this machine is everything you need. It has 5 nozzles to handle every job and a 16 inch wand extension (lance). A longer lance is available separately but not recommended and generally unneeded. The 20 ft. hose makes it easy to work well away from the unit without having to re-locate often and the trigger handle is easily and securely stored in a bracket on the left side of the handle. The engine is equipped with a low oil shut off for engine protection. And it has a manual shut off switch for when your job is complete or it's time for a break. The choke and throttle controls are separate for easy starting and power adjustment. For convenience it has a large fuel tank which reduces time loss due to refilling the gas on larger jobs. Pneumatic tires make it very easy to maneuver and store and it's over all size allows limited storage space. Though it doesn't come with a soap bottle attachment, it does have a pick up tube (siphon) that can be placed into any bottle with a handle and hung from the machines handle. Using the black spray nozzle allows soap to be applied. This is a tough machine that requires care and safety while in use so wear appropriate gear and avoid spraying anything you don't intend to clean as it will shred wood surfaces if you are too close. And NEVER spray near animals or people. Read and understand all safety procedures before using.

Simpson Clean Machine by 3400 PSI at 2.5 GPM Cold Water Residential Gas Pressure Washer – I am wondering what is going on with the production department. I received my pressure washer and like many others, there was no wand in the box and it has the wrong label on the unit (3000 PSI) washer. After waiting over a month to get the wand, I went through the start-up guide: filling with engine oil and gas, hooked up the water and started the engine. I tried it out cleaning some outdoor furniture which it did a good job getting dirt and green off. After about 20 minutes I noticed the pressure washer shaking oddly. I stopped the engine to inspect and found the 3 of the 4 serrated flange nuts used to mount the engine and pump to the frame had vibrated loose and were on the ground under the unit. The fourth nut was loose but not yet off; four 5/16ths bolts sitting in the mounting holes were keeping the engine and pump from falling off the frame. I don;t like serrated flange nuts for anything that vibrates, I replaced them with nylon insert locking nuts. The engine runs well and starts easy, even after stopping it and restarting it several times for different durations. The frame is heavy duty and it rides on pneumatic tires not solid rubber. The high-pressure hose is 25 feet long; it sprays high-pressure water and doesn’t leak where it shouldn’t. Documentation for start-up and operating manual are easy to read and understand. Considering the issues I experienced, this could be a really good machine, but I won’t recommend it; there are other companies that make pressure-washers. The mistakes with mine are just from sloppiness by people who don’t care enough to do a good job.

Ok, let's address one thing first. Just like many other recent reviewers, my Simpson Clean Machine 3400 PSI 2.5 GPM Gas Pressure Washer arrived without the Spray Wand (also called a lance) and with incorrect badging stating a 3000 PSI/2.3 GPM capacity. Obviously an issue at their factory, but given the pandemic and it's radical effect on normal operations at many companies I'm willing to overlook that initial failing. I contacted Simpson's Customer Care Team and was impressed with their response. They were able to ship out the missing spray wand and a new handle with the correct badging immediately and within days of my request I was up and running. So, an A+ on customer service. So, about the machine itself. This is a very nice pressure washer for the money. I've spent several days now pressure washing my house and gutters and I'm very happy with the operation and design. The 208cc engine has plenty of power and gives every bit of the stated 3400 PSI spray. The large gas tank allows for several hours of run time between refills. The included 4 spray tips allow for pressure and spray control, and the handle has handy storage for the tips and the spray hose. A separate bracket on the handle holds the spray wand/gun when not in use. The 25 foot spray hose included is fine, although a little stiff. Set up is very simple, just attach the handle, add the included engine oil (they even include a little label that folds into a funnel to help with this). Engine starting instructions are printed right on the machine. Overall, I'm very pleased with this product and expect years of service - highly recommended!

There is a lot to go through here so, please bear with me… First off, as many others have mentioned, I did not receive the spray wand with mine either. I called customer support and was informed that they would ship me a wand, but they are currently back ordered. And would be about 2-weks. After a month, I went to my local Home Depot and purchased a wand because I wanted to pressure wash the driveway. The next problem is that this is labelled as a 3000psi but the website says 3400psi. The machine looks EXACTLY the same as the pictures on the website. So, I’m not sure if this is a label issue or the website is inaccurate. As far as the operation of the pressure washer, it starts easily and I ran it hard for almost 2 hours. The gas tank is large and holds enough for this amount of runtime. The pump kept up no problem and I was able to get a lot of pressure washing done. I used all the tips which include soap, 45, 15 and 0 degree. For my driveway, I think I will need a disk as the tips work great to get the grime off but they only cover a small area. I did notice a drawback in the trigger design. The hose connection is very close to the trigger guard and I had a hard time getting the hose on and off. The machine is easy to wheel around, easy to start, works well. In my opinion, if the wand had been included and the labeling was accurate, they would have a very good product. However, due to the current shortcomings, I cannot recommend this product. Hopefully they get it fixed.

The labels are confusing, says 3000 PSI versus listed 3400. The paper work is also confusing as to what I might have. I was missing the wand and no idea when they'll send me one,,, I borrowed a neighbors wand to do this review. .... Assembly is minimal and it came with the needed engine oil. It has what appears to be a strong and supple hose rated at 3,700 PSI and a pistol grip that is easy to use. I like the wand bracket for when you're taking a break.... The velcro strap to hold the hose when not in use is nice but question how long it'll last. I can always put a bungee cord or old buckle belt on it for storage... The engine has an adjustable throttle and is fairly quiet... The unit is light weight.. I comes with 4 tips that will handle several conditions. I used the unit on 3 occasions for about 10 minutes each and it seems fine... . I would prefer the rear brace be a bit longer as it can be slightly awkward to move..

I was excited to receive the power washer until I opened the box. The box was missing the wand attachment that all the fittings plug in to so I can not use it. To date it has been 4 weeks and no wand. The unit is light weight. The only assembly is the handle and wand holder. Oil is supplied and there is a siphon hose for soap. I prefer a container to put soap in attached to the machine instead of using a siphon hose to pull from a jug that is sitting on the ground.

This unit is a Simpson 3400 psi gas pressure washer which was mislabeled as a 3000 psi washer (strange). The engine is top quality which has started for me every time on the first try (impressive). Nevertheless, I was very disappointed to find the engine bolts loosening up after about the first 1/2 hr of use. I couldn't believe it, all of a sudden the unit started making a racket - when I investigated I found nuts and bolts laying on the ground. Another negative, is trying to coil up the hose for storage - it's a headache. I am happy with the power of this machine and would have rated it higher if it wasn't for the issues I've described.

I needed something to replace my old pressure washer that I have had for about 20 years. This looked to be pretty close to the same features. And amazingly it prices out less than I paid for my old one 20 something years ago. I don’t know if it will last as along. Time will tell. But in 20 years I’ll be about too old to be using it anyway. The cart design is not perfect in that it lifts up at the back to be moved so you essentially lift and pull to move it. It would be easier to move if the wheels were at the back. My old one had the wheels at the back and you tilted it and pushed it. That older one was just very slightly easier to move around. But this is not a real heavy machine so it is still pretty easy to move around. The hose holding mechanism (a nylon strap with a catch to hang on a braket) seems cheesy at a glance since my old one had a fixed bracket. But to be honest I think this works better because that stiff pressure washer hose never sat well on that bracket and had a tendency to jump off when the washer was being moved. Tis wraps around it and secures it well. So this is probably not a bad design on the hose holder and will likely work better. Seems to be good so far. And down the road it could easily be replaced with a bungee if the strap deteriorates. The holders for the tips are just rubber seals you push them into. This might not seem as well made as some where they snap in (like my old ones) However this is easier to pop them in and out of. And I’m all about things being easier so I'm good with this. All in all it is not a bad machine. I have a lot of concrete to clean so this should do the trick. Last year I paid to have my patios, drive and house pressure washed. And while that was certainly easier for me I did not get the same quality job as when I do it myself. And I paid more for all that work to be done than this pressure washer costs. If I could get a really good job done I would not mind paying someone else. But if you really want something done well do it yourself. The packaging was prety well done with lots of padding in a very large box. The only problem I had was the bottom of the box was split at the sides and the lower half of the wand was missing. I figure I just fell out during shipping (I searched the box thoroughly). But I just grabbed one at the local hardware store for $16 rather than try to track down the company and get a replacement. It was not worth my time and the wand uses standard pressure washer fittings. So it is easy to buy parts or wand extensions. In my first use it seems to work just as well as my old unit and it knocks the heavy algae buildup off my concrete well (see photo). One thing that is definitely better than my old unit is the 4 stroke engine and not having to mix gas and oil. On the whole I’d say this is a good little unit for the price.
