This 4400 psi unit has incredible power. After about 4 uses, something inside the spray gun failed causing it to spray continuously even when the trigger wasn’t being pulled. It was still within the 90 day accessory warranty, so they quickly sent out a replacement (I had it within 3 days of calling). I only wish the accessory warranty was a bit longer. Had this happened just two weeks further out, it would have technically been out of warranty.

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.

I bought this machine just under a month ago and I could have not been any more impressed. My machine did come with two scratches one on the pump and the other by the pump oil cap but not a big deal (probably just from shipping). I have used it twice already probably running about 5 hours total. Had the pressure gauge set in the middle and the throttle only up to half way just to ensure break in period was smooth and even with that it was more than capable with what I needed it to do. The wand and hose with the quick connects were definitely a huge upgrade and super simple. Overall I do not think anybody could go wrong with this. From the once a year user as a homeowner or even a business owner could get some serious work done with this machine.

I bought this i think in August of this year and I am super pleased with it The pressure washer has more than enough power to clean anything you want in half the time you used too with lower psi washers The only draw back for me is that I am a 73 year old man and it is a little hard for me to pull start wish I would have bought electric start This is by far the best pressure washer I have ever owned I have had three others Would buy again in a heartbeat

Bought the Simpson 4240 at Lowes along with a Surface Cleaner. First use was our front driveway and side walks - the combo did a GREAT job. Between the Simpson's high pressure/high volume output with a stainless steel 15 " surface cleaner - the job went quickly with wonderful results.

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.

Purchased a couple of weeks ago and just used the unit. I have only used with the Turbo Nozzle and must say Unit started on the first pull, had plenty power and worked perfectly. Would and have already referred to a couple of friends to also purchase. I had quite high expectations and it is always nice to buy something and it works better than anticipated. I am sure I will have many years of Operation!

Bought the PD4240 for may 500 feet of concrete driveway and also the many retaining walls I have. Was afraid it would be big and cumbersome and hard to store but it was not, not any more difficult than my old 2100 PSI machine. It starts easily and is surprisingly good on gas. I love the adjustable output pressure, and it works well with the attachment for driveway cleaning, also a SImpson product.

I read reviews pros and cons and night mares I have been using power washers for years and to me you want a tool that out performs your exspectations I am extremely satisfied with my purchase and its performance I must say it does such a good job it can be dangerous to ameratures

I went with Simpson on the recommendation of a friend since he already had a Simpson. I really am glad that I took his advice. I already had a smaller power washer from another manufacturer but was having an issue with it and decided to purchase a new unit. I also wanted to purchase one that was a little more powerful. I couldn't be more pleased with my selection. The Simpson completed the patio cleaning job in half the time that it took me with my previous washer. Thanks Simpson.
