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.

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.

Bought this machine 2 weeks ago. 15 hours on it so far and it performs extremely well in every way. Very well built, easy to start and really puts out the power I need to wash the siding, cars, concrete, etc. Well worth the cost. Buy this with confidence.

purchased to pressure wash 180FT of wood privacy fence. Wow looks like new. Supplied water thru garden hose from house faucet worked perfectly,. now I have washed the house ,sidewalks and truck. Can't go wrong with Honda motor, first pull every time. compact lightweight well built. Now have lots of friends that need to use it.

I made sure I had a unit with a Honda motor first... Upon our purchase I started to power wash "Everything" I could find around the house. It was effortless and a bit fun... "Why"? We saw how clean the brick, driveway, curbs, stone and siding looked afterward that we decided not to sell our home for a few more years. Our last two units never cleaned or worked this well, and it is easy to change settings and pressures; a strong and sturdy machine for sure. Now for the down side; I have no mount or storage point for the wand and the nozzle attachments continue to fall out of their storage device and I have lost two of them already. This needs to be addressed immediately.

I've been cleaning my TimberTech deck - 18x12 plus 2 sets of stairs - using my brother's power washer for years. It's always taken me about 2 days and 5 tanks of gas to complete the job. With the Simpson, I completed the job in 3 hours on just over 1 tank of gas! Now my brother's borrowing the Simpson!

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.

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 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 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...
