Overall it's a good pressure washer. Have approx 5 hrs on it. I did add an induction type hour meter for maintenance intervals. The Honda motor and CAT pump are great. Starts VERY easy with the nozzle removed and the trigger handle wedged open. Remember to crank down on the unloader to get the pressure you want. The frame, not so much. Tends to 'walk' when using. Within the 5 hrs, the 'feet' were worn down. I ended up pulling the feet off my 20+ year old pressure washer (that never wore out) and put them on the Simpson. Also used some Destaco type push/pull clamps to add brakes to the wheels so it won't move around. May end up adding some vibration isolators between the engine and frame like my old Craftsman pressure washer had. Used some 1.25" galv conduit and raised the handle up around 12". Added another hose hanger and a basket to put accessories. I'd buy it again at the price point.

Im happy with it. But what I have found is that you have to understand what the GPM is good for. I have another pressure washer that is 20 to 25 years old, because I bought it used 17 years ago. Honda Motor and Cat pump are still going. But it is 4.5 GPM. If your washing down and cleaning a driveway the 4.5 GPM is much better. If you are washing a car, washing down a truck bed, using a small surface cleaner to clean the garage floor, the 2.5 GPM is good. The smaller pressure washer is much more quiet than my larger one. You can not adjust the pressure and it does not have a pressure gauge. But you can use an inline pressure gauge and use larger tips to reduce the pressure. I have 4.5 GPM tips from my other pressure washer and some warn 4.5 GPM tips. So, I can use those for lower pressure.

Easy to assemble. Runs well. Works well. However, when removing the little black rubber plug on the CAT pump redbvent cap which must be removed before using the pressure washer, just the top of the rubber plug came off…leaving the plug itself still in the red plastic pump vent cap. I had to remove the red vent cap and disassemble it to get that plug out and then reassemble the cap. Also after the initial use of the pressure washer I found a nut on the ground underneath it. This nut was not tightened sufficiently in the factory. I reinstalled the nut with sufficient torque and checked the others on the underside of the deck.

I wanted a pressure washer that was powerful enough to do jobs but light enough I could easily lift it into the trunk of my Toyota Prius. I found it in this one! The first time I used it a couple nuts came off and bolts were loose. I was thankfully able to find them in the yard and tighten them up. I only use ethanol free fuel in it. I also upgraded to a longer hose.

Just replaced my old system that blew out the pump. Motor was still running fine but the Cat pump was pricy. It lasted over 10 years so I wanted the same Honda motor and Cat pump. The new one was a little stubborn to get started for the first time, but once it started it performed perfectly. I expect to get at least 10 years from this machine to as well. The aluminum frame makes it a bit lighter and smaller which makes it easier to haul around.

I bought this pressure washer about three weeks ago. It came in about 4 days which was pretty fast. Why it arrived the box it came in was all beat up. It only had one pi ce of tape across the top and bottom. The plastic on the pressure washer gun was broke and the wand bent. And it was missing one of the rubber foot. I called water cannon where I bought it and told them about it but they could care less. ( I will never buy anything from them again). So I called customer service at Simpson and they were very nice. They sent the parts out in three days. As for the pressure washer I have used it theee times, it is amazing. A lot of power and starts on the first pull. The Cat and Honda engine are awesome. If it wasn't for the packaging issues I would have given this pressure washer five stars. Simpson needs to look into their shipping department. All in all it is worth the money.

We purchased the ALH3228-S to replace an older pressure washer purchased from a "big-box" discounter. The ALH3228-S has a lightweight aluminum chassis that works, is easy to maneuver around the shop or farm. The washing effectiveness is better than expected, seemingly better than the specifications. Glad we bought this rather than the cheapest unit available--money well spent. Should last us for home, shop, and farm use. . . for a long time. Thanks.

Purchased this model mainly for the CAT pump and the Honda engine, the aircraft aluminum frame was a bonus feature that closed the sale. I've only used it for a few hours so time will tell if will be a great long term purchase. The reason for leaving this review is to tell purchasers to READ THE INSTRUCTIONS! You MUST attach the garden hose and fill the pump with water by squeezing the handle on the wand until water comes out BEFORE starting the engine. Once you have water in the pump turn the hose down to a low flow then turn the gas on, apply choke then squeeze the handle on the wand again to release the water pressure THEN start the engine and fully open the garden hose to have maximum volume. When done turn the gas off and let the engine burn off the fuel in the carburetor. Don't let ethanol gas sit in the fuel tank longer than 30 days without emptying the gas tank. Old ethanol gas is ruining ALL small engines.

Purchased two weeks ago, was well packaged with no damage. Setup was really simple. So far have used this once to clean our fence, had great pressure, much stronger than the previous electric unit owned. Honda engine started on the first pull. Excited this unit has the CAT water pump which should last over time.

I bought this in December and finally used it in April 2026. This bad boy is awesome. I had a pressure washer that I bought 15 years ago - that worked so well. I didn't realize how important the Honda engine was! Bought a Dewalt, with a chinese engine, it NEVER worked, even the certified repair shop could not get it running ... so I was on the hunt for new pressure Washer ... this one just does a great job. Now time will tell, but I think this is a winner.
