I bought this power washer about a month ago from a local box store and used it for the first time this week. I've owned three other power washers from different manufactures, all under 2500 psi units. The inaugural use was to wash my car and trailer, along with a test section of my driveway. When I first fired up my new Simpson machine, I was impressed with the over all volume. It was somewhat noisy, but way less noisy than any of my previous machines. Next I have s immediately impressed with the power. Aachine producing 3200 psi is fantastic. I tried the soap attachment with a mild diluted car cleaning solution and it worked well. My trailer had some algae/mildew build up, and the machine blasted it right off. The test section of the driveway went effortlessly and quickly. My only complaint is the the machine seemed to "walk" a little bit while in use. Not much, but some (way less than any other machine I've ever used). I plan to use the power washer this summer for some handyman work in the neighborhood. I have three houses lined up, four decks, and fence, and 4 driveways. I'll update the review after I complete the jobs. At this point, the machine doesn't disappoint and I'd highly recommend.

I used it only once. Very powerful. Was somewhat difficult to start but when it got going, it blasted away the accumulated moss and fungus from off my driveway. I added quick couplings going from the washer to the hose from the hose to the wand to enhance user friendliness.

I bought this sprayer to replace a seized one on house cleaning job. The pressure amazed me, as did the amount of time I got from one tank of fuel. I use this washer for lower power applications by simply lowering the RPMs some. The only issue I have with it is the wand trigger gets stuck on occasionally and now always has some flow coming from it and continuously loosens where the bar/control handle connect to each other. I would have liked to have a better hose and control handle. If the wand was up to the speed of the res of the washer, I would have given it 5 stars.

This is an excellent unit with a Honda engine. The pressure washer performed very well from the beginning. The unit is well balanced and of solid construction. The pressure line is long enough to keep the unit out of the splash/dirt debris area. The engine performs well during "prolonged" operational periods. The only issue noted were the four (4) engine attachment bolts to the aluminum platform were only finger tight and two (2) fell out during the first hour of operation. I re-installed the two and tightened all four. No further problems or issues. Overall, a very well designed unit with plenty of planning in it's creation.

Purchase the ALH3425 about a month ago and have used it numerous times. I have never owned a gas powered washer before, only electric. This machine is far superior to anything I have ever owned. The setup and initial operation was extremely easy. The washer has performed beyond my reasonable expectations. I would recommend this for any residential or light commercial uses. Five star all the way.

I PURCHASED THE PRESSURE WASHER 3 WEEKS AGO AND I LIKE THE PERFORMANCE A LOT, JUST KNOWING THAT A HONDA ENGINE WAS USED AS A MAJOR PART OF THE MACHINE TELLS ME THAT SIMPSON IS CONCERNED ABOUT THERE QUALITY. NORMALLY I WOULD OF RATED THIS WASHER A 5 STAR BUT, 1) I HAVEN'T USED IT LONG ENOUGH TO VALIDATE DURABILITY, 2) WHEN THE WAND IS IN THE HOLDER AND I MOVE UNIT FROM POINT A TO POINT B THE WAND TIP CLANGS AGAINST THE ENGINE, NOT A MAJOR CONCERN BUT WHO WANTS TO SCRATCH UP THE PRETTY PAINT JOB ON THE NEW HONDA ENGINE, 3) I WOULD LIKE TO SEE THE HANDLE A LITTLE LONGER OR ADJUSTABLE FOR EASE OF MOVING UNIT. I'M GOING TO RATE IT A 4.5 STAR BUT SEEING THAT IT ISN'T A OPTION IT WILL HAVE TO BE A 4 STAR...

I have only used this one time but the Honda engine ran great! I also liked the 35ft hose. It had plenty of power to reach the dormers on my house. I also like the aluminum frame, it keeps the weight down so it's easier to load by yourself. I just wish the handle was a little taller.

I recently purchased my Simpson power washer 3400 psi, model ALH3425, from Lowes and I'm very pleased with it. The unit has more than enough power for around the home use. I've cleaned some old stain off my exterior deck already with it, and was very pleased. I also plan on power washing my driveway and my privacy fence with it soon.

I purchased this unit to replace an older 2800 PSI Generac. I have a small side business I use it for; decks, houses,etc. Performs flawlessly. The 3400 PSI pump is great for my needs. Love the Honda engine. The only thing I wish it came along with were quick connect fittings. Would buy again.

I bought this in 06/15 and have used it for 2 long (for me) days. I cleaned my long driveway and back porch. This washer was easy to start, didn't jump around while running and did an a remarkable job cleaning off years of muck and stains from the drive. I also bought a 36" wand extension and a 15" round surface cleaning attachment. This made it easy on the back and a pleasure to see the results.
