I have has a smaller electric unit (Westinghouse 2K), which I still love and will use a lot for smaller jobs. However I have a lot of hard surfaces on my property and, living in the Pacific NW with the rain, trees and shade means I also have a LOT of moss and other organic buildup to deal with. I have done a lot of research. I've purchased other pressure washers. I finally decided to make the investment in a commercial grade machine because I wasn't getting the results I wanted in any reasonable amount of time and my electric simply doesn't drive a surface cleaner. Manually wanding my driveway was taking days with the electric and that was just focusing on the most important areas. So, with some advice of a trusted friend who owns a rental company, I decided to take the plunge on something with enough pressure (4k PSI) and GPM (3.5 or more) to make a meaningful impact. All I can say is: Wow! In the first 3.5 hours of use, coupled with the Mekoh 18" surface cleaner, I was able to clean 3 times the amount of moss-coated (thick in many spots) surface compared to the surface cleaned in 3+ days manually wanding. I also have a sports court which needs love and will be my next tackle. The obvious concern I've had is not stripping off the paint, but still getting the surface clean. So I wanted something I could "back down". While the pump on the 4240 has a regulator, I actually purchased the Simpson pressure regulator and it seems to work quite well. I suppose I could use the pump regulator in tandem with the extra in-line Simpson regulator to really dial it in, but I'd prefer not to muck about with the pumps factory settings. To address some of the concerns I've seen in other reviews: the unit arrived in excellent condition obviously all new and delivered on time. The modest assembly of the draw bar and wand and hose caddy was a matter of two minutes, easy peasy. The Honda engine instructions and the Simpson quick start guide were easy to follow in terms of adding the oil, fuel and then start up. Start up was just as straightforwardas the manual said, and, as long as I was following those instructions [ahem], it started on the first pull every time. I did make a note that others had said it's helpful to pull the trigger when starting and so I did that (but not always, and even when I didn't, and I had the switches and throttles in the right position, it still started on the first pull). While I have only used it for a short time, there was absolutely no evidence of oil leaking or any of the other mechanical issues mentioned. If this changes over time, I'll come back and edit this review. Everything about the pressure washer is commercial/contractor grade. The Monster hose is just that - it seems like it will withstand anything but does take extra effort to maneuver. In all, the unit does require strength and some stamina to operate (because it's so strong) and you'll need a ramp or some help to get it into the back of a pickup. But if you compare it's effectiveness and the substantial reduction of time, I'd say overall that it takes much less effort to get amazing results than less powerful models. Bottom line: if you're tired of putting up with lesser units, and have the budget for this fantastic monster, I highly recommend it.

I spent a long time researching pressure washers before buying this Simpson PowerShot, and so far I’m very impressed. The Honda GX200 engine starts easily, runs strong, and gives the machine a genuinely commercial-grade feel. It has more than enough power for driveways, siding, fences, patio cleaning, and heavy grime removal. What really stands out is the build quality. The frame feels solid, the tires roll well over rough ground, and the hose and fittings seem much better than the cheaper big-box-store units I’ve used before. It definitely feels like a machine designed to last if you maintain it properly. Cleaning performance is excellent. The combination of 3500 PSI and 2.5 GPM hits a really nice sweet spot for homeowners who want serious cleaning power without stepping into extremely expensive professional rigs. Driveways and concrete clean up fast, especially with a surface cleaner attachment. A few minor downsides: * It is heavier and louder than entry-level machines. * The included hose is decent, but some users may eventually want a longer or more flexible upgrade. * Like many Simpson units, it vibrates a bit at idle, though that seems normal for these larger single-cylinder engines. Overall, I think this is an outstanding value if you want something significantly better than a basic homeowner pressure washer without jumping into full contractor pricing. Feels powerful, dependable, and built to work. Would absolutely buy again. The PS61002-S is widely marketed as a “professional-grade” or heavy-duty homeowner unit with a Honda GX200 engine and 3500 PSI / 2.5 GPM output. ([old.simpsoncleaning.com][1])

I've only had the power washer for one month as of now. It's a small unit, but very strong. No issues so far with the pump or engine. There are two reasons why I didn't rate this 5-star. First, and most importantly, the engine is shipped without oil (understandable and normal) so we need to add oil before trying to start it for the first time. It comes with a 16 ounce container of oil, but the engine requires 20 ounces. I wasn't aware of this and needed to purchase another container of small engine oil which wasted another two days before I was able to get it. Second, the holder for the power washer wand/nozzle doesn't hold it in place that well. The wand is always falling backwards or sideways while in the holder. I realized that if the wand is disconnected from the hose, it sits in the holder fine... but who wants to disconnect it and reconnect it every time? I would still recommend the unit to others so far.

Pressure washer was easy to assemble. Took 20 minutes to unbox and put together including adding fuel and oil. started right up and I was able to pressure wash my walkway quickly. Has lots of power. I was wanting one with the honda GX390 motor and this unit is a good value.

I would highly recommend this Simpson Pressure Washer as it started on the first pull and runs like a champ. Super simple and only takes about 10 minutes to setup for the first time use. Well built and Great pressure for plenty of cleaning power!

This is a powerful compact pressure washer! I have only had it for a few weeks but so far it has made short work of cleaning my patios, driveway, and fences. It was easy to set up and started on the first pull. The hose that comes with it is only 25' long so I purchased another 50' hose so that I did not have to keep moving the pressure washer. I also purchased the Simpson Turbo Nozzle which works very good on the patio and driveway. I would not use the Turbo Nozzle for cleaning the house or fence as it could cause damage really quick.

Love this Power Washer. I have owed different washers made by different companies( Craftsman, Generac) and this one is my favorite. The Honda engine is a definite plus. Engine starts on the first pull and has less compression resistance on the pull. Unit is also not as cumbersome and the pneumatic tires make it easier to move around on gravel and turf surfaces. If you want a power washer for heavy farm use and not just some city-slicker unit, this is the one for you.

Style: 4400 PSI
This machine is a replacement for an older Kärcher 3100 PSI that finally gave out. The difference in cleaning power is immediately noticeable. The combination of 4400 PSI and 4.0 GPM is what separates this from lower-end electric and gas machines — higher pressure plus more water volume means faster, more thorough cleaning. I used it on decks, a patio, and siding, and the results were excellent. Assembly was straightforward and packaging was solid. Build quality is generally impressive: real pneumatic rubber tires (not cheap plastic), a quality hose with quick disconnects , and an AAA pump that builds pressure instantly — no lag when you pull the trigger like I had with my old machine. The CRX 420 engine appears to be a clone of the Honda engine. It started on the first pull, and ran without issue. The soap dispenser also works noticeably better than what I was used to. One frustration: a small plastic knob shattered during assembly. I tried reaching customer service via email and phone. I ended up buying a replacement at Menards for $5, so it’s a minor fix — but the lack of support response is worth noting. Bottom line: this may be overkill for someone who pressure washes once a year, but if you’re tackling bigger jobs or want a machine that will last, it’s worth the investment.
