⭐⭐⭐⭐⭐ 5/5 Stars I recently purchased the Simpson 3400 PSI Gas Pressure Washer with the 15-inch Surface Cleaner, and I couldn’t be happier with the performance. The pressure washer has plenty of power for cleaning driveways, sidewalks, trash cans, and home exteriors. It starts easily, runs smoothly, and gets tough jobs done quickly. The 15-inch surface cleaner is a huge time saver. It cleans concrete evenly without leaving streaks and cuts cleaning time in half compared to using a standard wand. The build quality feels solid, and the machine is easy to maneuver around the job site. As a small pressure washing business owner, this setup has been a great investment and has helped me deliver professional results to my customers. I highly recommend it to homeowners and anyone looking to start or grow a pressure washing business. Excellent power, great value, and reliable performance! ... show more

    • Great Pressure Washer
Style: 3400 PSI + Surface Scrubber
I’ve been using the Simpson 3400 PSI gas pressure washer along with the 15-inch surface cleaner, and this setup has been a solid upgrade from my previous equipment. The pressure washer itself starts easily and delivers plenty of power for driveway, siding, and patio cleaning. It handles tough grime without needing multiple passes, which saves a ton of time. The engine runs smoothly and feels reliable, even during longer jobs. The 15-inch surface cleaner is where this combo really shines. It cuts cleaning time in half compared to using just a wand. Coverage is even, with no streaking, and it glides well over concrete. It’s especially useful for larger areas like driveways and sidewalks. ... show more

    • A lady in her retirement years can start & run this! machine!
Style: 3400 PSI + Surface Scrubber
My husband had it put together in under an hour! Took it outside, followed instructions for adding oil, connecting water, etc. and it fired right up! Showed me how to use it and I did a quick cleaning of one of our sidewalks. It was easy for me to start and handle and did an excellent job! The black build up is gone! Next I’m going to do the white vinyl fence around our paddock. Excited to tackle that project which has also been waiting a few years! ... show more

    • The magic wand doesn't work
Style: 3400 PSI + Surface Scrubber
First out of the box , the15 " wand leaked and could not use, waiting to see if they replace it, second, The power gun and wand was a Dewalt and not a Simpson, I'm guessing they will tell me I have to get the wand from Dewalt, I didn't purchase Dewalt they did, we'll see, for that reason I gave them a 4 star. I'd love to give them a 5 star, the pressure washer itself. I am very pleased with, runs like a champ and it's quality representative of the Simpson name. I have 3 PW'S and they all run great. I will change my 4 star to a 5 star if they replace the wand instead of me dealing with Dewalt ... show more

Review Image by John Forsyth
This is ideal for my situation, I have a large house and a long concrete driveway. The 3400 psi is more than enough for the job. I would say this is just one step below the commercial cleaners. It was easy to assemble and easy to start (Honda motor). I also purched a 15 inch surface cleaner for the driveway. My 35 year old daughter, who is small, did most of the driveway with little effort. I would definately recommend this power washer for any homeowner. The price was excellent for a 3400 psi washer. I attached a picture of what it did for my driveway. ... show more

    • Spring/Fall's Best Tool
Style: 3400 PSI + Surface Scrubber
When you live in a deed restricted community that has a homeowner's association, certain things are inspected and expected every year. This includes getting rid of any mold or algae and siding and driveways that comes from oak trees, dead leaves, humidity, etc., all of which happens to homes in my neighborhood. Most of my neighbors hire someone to pressure wash their houses/driveways at least once a year. I, on the other hand, have always been a do it yourselfer, and rationalize that doing a job yourself and not paying for someone else's labor, pays for the tool after a couple of uses. Since I am on a cornerlot, I have twice the sidewalk as my neighbors. Thus, the purchase pays for itself. After hours of internet research, I picked this one, because it had good reviews/ratings, and was the best bang for the buck, as it had the pressure to meet all my residential needs. Additionally, while researching, I learned that GPM was equally as important, as are the larger wheels and taller handle for easier mobility. NOTE: I am not one to read manuals. However, I would recommend doing to when it comes to operation. It is not hard to use, but needs to be done in a certain order, including minor maintenance storage. It cleans everything well, especially windows, but getting too close to walls will take paint off. So, no need to go larger. ... show more

    • Failure after 5 minutes of usage **Update***
Style: 3400 PSI + Surface Scrubber
I was looking forward to using this pressure washer as Simpson is one of the top brands in the business. I received the pressure washer and everything arrived intact. It was simple to assemble and instructions were easy to follow. Added oil and gas and it was ready to go. Easy start up and was working great until it wasn't. Engine shut off and would not restart. I then discovered the spark plug wire had come unattached and when I checked it, the inside of the plug fell out. Unfortunately this could not be repaired and now I have to go to a service center for a warranty repair. A WARRANTY REPAIR AFTER 5 MINUTES IS UNACCEPTABLE. Now I have to wait 3 weeks or more for the repair. A NEW pressure washer that has to be repaired should be replaced and if not then a significant refund should be issued! This is the chance you take buying online and my advice would be to buy locally for this exact reason. Had customer service been authorized to replace the unit rather than repair the unit I would have no issues but now I am afraid this unit may give me problems for as long as I have it. **Update: I wish this was a happy ending update but as of today October 7, 2024, my NEW pressure washer is still with the Authorized Repair Center. After repeated calls, trips to the shop, conversations with warranty, the issue is still unresolved. I keep getting the same response, we are waiting on a part. No one has reached out to me to keep me in the loop during the process, the only way I get information is when I seek it out myself. I have been very patient but no one seems to care. At this point I just want a refund so I can go purchase another unit. I will keep you updated so that you may learn from my experience. ... show more
