Work Horse

Best machine I have used. Plenty of power, well made. I used to clean concrete at large church property. Cleans great, fast and easy. Seriously good engine, pump, accessories and frame. Easy to move around and has a long hose, reducing time needed to move machine.

More then expected

I will start that I have looked at buying a pressure washer for over a month. I have looked at and read reviews on just about everything out there. Then I became familiar with the capability of the different psi’s. 2800 psi seems to be most common however after using one it was very much underpowered even for home use. There is quite a price jump in washers say 3000 psi and up. After seeing a hand full of reconditioned washers in the store I was even more apprehensive one picking a brand. I knew I wanted a 3000 psi or higher. On this pressure washer a Simpson 4400 psi for the price was a steal. The reviews were not so impressive. After reading over 50 reviews I made my choice to give this a shoot. The thing that stood out more then the problems people were reporting was the high level of customer service Simpson offered to have repairs made. Anything with an engine will breakdown and have good customer service makes all the difference. I have not had any problems with this pressure washer as of yet. I have put about 40 hours on it so far. I can say I have gotten my money out of it already so I’m rather pleased.

Great Unit

Worth spending more to get a commercial grade pump and honda engine. This unit should last a very long time assuming you take good care with it. I wanted at least a 4gpm pump so i can clean faster. One thing to keep in mind is to turn off motor if not spraying for more than 1 minute. This will greatly add longevity to your pump life.

Awesome

I bought this to drive a General Pump Hammerhead 20" surface cleaner. That think was floatin' like a hovercraft. If you need the pressure and can afford it, get the Honda. I never cranked it that it didn't start on the first pull INCLUDING the very first start.

As Described

I bought this a week ago and it is performing as expected. I am looking forward to see the longevity and issues with the product. For now, the only issue is the oil container. You need a funnel to put in so it doesn't spill. You would think they would have figured it out by now how to make it easy, and the fuel gauge is hard to read (should be marked).

So Far So Good

I recently bought this for power washing driveways and walkways. The power is a noticeable difference over my 3200 PSI unit. The only issue I have not figured out yet is the soap hose. When the unit is off, the soap is pulled through the hose. However, when the unit is running, no soap appears to be pulled into the unit. Not sure if the problem is the unit or something I am not doing correctly.

Super Blasting Power!

I have two ot this Hydro Blasters, we cleaned TWO Cooling Towers in Two Days only using the rotating tip. The project was scheduled for fur days, so we didi it in half the time. Definitely this is a great source of equipment for your job. Very efficient gasoline engine gives you four to five hours for one full tank (Amazing)!!!

professional quality product

the unit just as presented in ads. while this unit will be used in my farm application it will perform a commercial level job. I compared many brands and spoke with my brother who has a cleaning business. he had a smaller simpson it works great. he is waiting for my review to order one. Please note to anyone reading this review be honest with yourself as to want type of job you are doing. don't buy less and expect more.

Simpson 4240H Pressure Washer

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!

One Powerful Pressure Washer

I purchased this unit recently and used it for a couple days. It is very powerful and exceeded my expectations. The engine started with a couple pulls and I had no operational issues. The hose is very heavy duty but is somewhat cumbersome to use. The wand was great and nozzles met my expectations. The one area of improvement could be the hose.
