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.

This thing is big, and heavy. The only reason I am giving it 4 stars instead of 5 is because of the typical terrible handle and lance holder. Other than that expected deficiency, setup was easy and started easy, sounds tuned. The power is something you have to get accustomed to when in use.

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.

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!

Appears to be a well constructed piece of equipment of good quality. It has a Honda engine that I have great success with on other power equipment. It is very stylish and the color (basic black with silver accent) compliments my other equipment . I hope this helps those considering a power washer..

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.

I read a lot of reviews before buying this unit and Simpson's reputation as a leader in building these played a key role in my finally selecting this unit. I might have overdone it; the thing is a BEAST of a machine. With normal proper care, I'm assuming this will end up going to my grand kids. 4400 PSI will blow away anything you need to blow away. The whole unit is strong, big motor and the AAA pump is one of the best out there. Engine may be Chinese, but they may have learned a thing or two by now, it looks like a quality-built unit & it started on the 2nd pull. The hose is as stiff as a steel cable - guess that's what you need to hold 4400 PSI. One drawback is that once the engine runs, it tends to vibrate around in circles when placed on concrete or flat surface. I have to place it on the ground/grass to hold it in place. Those are about the only negatives. Make sure power is what you want, because if you are looking to get this unit, that's exactly what you'll get!

I am a homeowner with 9000 sq ft of concrete, rural property, with big driveway. In addition, I have a large garage, with 1100 sq ft of concrete and a boat garage with 1800 sq ft of concrete. I clean all a couple of times a year and this machine powers my BE 24" Whirl-A-Way easily, gets the job done fast.

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.

I purchased this unit for my home needs: driveway/patio cleaning, brick siding, deck cleaning etc. This thing is a powerhouse! Assembly was easy and starting is almost a breeze. The PSI and GPM may seem to be a bit much for residential use, but I was concerned more with time in getting a job done. Definitely quicker than a smaller unit and variance in price. Very happy with purchase.
