While searching to upgrade from a good homeowner 2400 psi washer to a slightly more powerful pressure washer, sub 4000 psi, there were 2 things the unit had to have. First, a commercial grade Honda engine and a CAT pump. This unit has both. Thre pressure washer was packaged very well and was put together quickly. The first time I used it I was impressed on how much better my surface washer worked on the sidewalks. With my old residential grade unit, the surface washer worked well and I thought it was normal to make several passes to clean. This new Simpson commercial unit paired with my surface washer cleans much faster and I am super happy I chose this unit. Most areas were cleaned with one pass, some with 2 passes with the surface washer. I did have an issue with a wheel almost falling off during my first use of the washer. At first I thought it was missing a washer and e-clip holding on 1 wheel. I contacted customer surface and they promptly returned my email. Rather that play email or phone tag, for under $2 I bought the replacement washer and e-clip. When cutting up the box I found a broken e-clip in the box. Simpson didn't forget the parts upon assembly, the e-clip just broke. I won't blame that on Simpson, rather their supplier of the e-clip, Hopefully, this pressure washer holds up well over the next decade or more like my old unit(which I keep as a back up.)

I got this a few weeks ago and have used it twice. So far, I am very impressed with the build quality and performance of this unit. I was looking to a pressure washer that would last me a long time - not a throw away unit that I would have to replace in a few years. Most units at the big box stores are throw away consumer products. Stepping up to this unit gets you both a commercial quality Honda engine and a CAT water pump. That's a great combo! It also came with quick release hose connections, which the cheaper units don't. I am very happy with it!

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.

I replaced my electric pressure with this a couple of weeks ago, what a difference! The Honda engine fired up on the first pull as expected and the Cat Pump is smooth and powerful. I knew better to buy that electric pressure washer and should have purchased this first. The frame is sturdy and should last for many years. the various nozzles will take care of many jobs, thanks Simpson for putting together a great combo!

I am a master ships captain and we don't do a lot of pressure washing but when we need a machine it has to work. We have had several washers and from experience we found a Cat Pump and a Honda engine are a great pair. The aluminum frame is very sturdy and a super addition around salt water.

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.

I'm a dentist and I did my homework and went for this pressure washer because of the Honda engine, the CAT Triplex pump, and Simpson has a good reputation. Easy to use and start. If the cord is getting tight when you are trying to Pull it, try to hold the trigger on the spray gun at the same time!

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.

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.

Followed the directions for startup and ran for an hour or so to test it out. No issues at all. Lightweight and powerful. The directions say this but be sure to let water run through the nozzle (hold the trigger down with the water on) for 30 seconds before trying to start. Otherwise it will be difficult to pull the starter handle.
