After a long and arduous delivery debacle, the unit arrived with cosmetic damages to the gas tank, I followed the initial fluid and start up procedures, by the book. The unit worked great for a while. I initially changed the pump and engine oil at 40- 50 hours, checked that the spark plug and air filter were in good condition. The unit worked relatively well after that....for the time that it did work. I used it for about 80 hours total and, while washing a livestock trailer, the AAA pump started grinding and releasing pump oil out of the water discharge and the motor would not stay running. This after it sat unused and idle for a couple of months. I performed the long term storage and winterization procedures to the letter and the unit worked well the first couple of times I used it. It was good at first and then it seemed to just fall apart....

I choose the 4240H because of the Honda GX390 motor and this unit can handle a 20 inch BE surface cleaner. My spouse wanted to use it to clean our brick house. Well, it's a bit to powerful for her 110 lb frame. The "kickback" when she pulls the trigger almost knocks her over, but she has learned to handle it. I recommend you buy from a local store because mine had a few dents from the UPS guys. You may have to pay an extra$20.

I previously owned a 3600 PSI unit from a different manufacturer; while it performed well, there is no comparison to this 4400 PSI unit. If you need a strong cleaning capability, along with a high-reach stream, this is the unit for you. Most impressive.

The Simpson PS60843 is a great machine I couldn't be happier with it, our building exterior has never looked better. The first two days we had it we ran it 8+ hr non stop and not a is single problem. The PW is quiet and has plenty of power, the 4400 PSI is great. We rented a sidewalk attachment to see if it was worth the cost and it was a great time saver and we will buy one in the next few months. If i have any complaint it is the two feet at the back of the cart they are wearing down quite fast.. The vibration of the unit on ruff concrete is no match for the hard rubber but I don't know what you could put their instead that wouldn't leave a mark on your sidewalks. all in all I love it and am very happy with it.

I bought this pressure washer a few weeks ago. I was hesitant about buying it with Simpson engine rather than Honda but the Simpson engine starts easily and runs fantastic With 4400 PSI, you can clean anything in no time especially with the 4500 PSI Simpson turbo nozzle. This is a Great pressure washer. Took about 5 minutes to assemble and put in supplied oil.

This is an extremely powerful machine made with quality parts. Well designed and sturdy. The only complaint I have is the holder for the hose and wand, although somewhat standard, seems ineffective as each can come off the machine while moving. A simple retaining mechanism for both the wand and hose holder would be welcome. Appreciate the Made in USA!

I'm beyond pleased with the performance and value of the PS4240 I recently purchased. The level of quality of the pump and the Honda engine is outstanding. The adjustable regulator is a great feature - and a key reason I bought this unit. I think Simpson should make more of a point that this feature exists, it does not receive adequate mention in your online info. I'm looking forward to years of service from this unit. I also purchased the SIMPSON Universal 15 Inch Surface Scrubber when I ordered the washer. This is an incredible accessory and a must-have for floors and driveways! Keep up the good work Simpson!

I bought this pressure washer as a starter unit for my pressure washer business. This pressure washer is very powerful. The hose is very well made however it is quite difficult to handle since it is steel braided. The Wand is of top quality. When it comes to starting, the motor starts almost instantly and it can hold a high rev for a very long period of time.

This is only review but the pressure washer is much better than the previous system that I owned. Plenty of power a bit awkward to move around. They might as well put a third wheel in the back or four wheels but this thing will clean anything. Oh yes, and I wish it was just a Key start for that amount of money it should be.

Used for a total of 2 hours until dramatic pump failure with water spraying everywhere! Had to take whole sprayer to service center 20 miles away. Been there for a week and still no news about warranty repair. Despite this (I assume I was just unlucky) it is an incredibly powerful machine and is a fantastic cleaner.
