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.

Fantastic pressure washer, only problem is that the needle/seat doesn't seal so it drains the tank into the cylinder and I had to remove the plug and pull the rope to get all the gas out then from that point on I have to close the fuel shut-off valve every time I stop the engine.

Bought this pressure washer a few weeks ago and couldn’t be happier. Did quite a bit of research and this guy was the most bang for my buck. Definitely potent for a homeowner, but gets the job done quickly. Honda engine started on first pull and pump seems to be of good quality as well. Very happy with this purchase.

I have had this pressure washer for about 3 weeks now and put it to work right out of the box and all I can say is wow, it performs above my expectations. It starts good usually 1 pull and I truthfully can not come up with any complaints as of yet. The pressure is great, I use it with a sand blast attachment and again no complaints. I recommend this pressure washer!!!

This thing is a beast. Very powerful. With the 15"flat surface cleaning disc I cleaned my driveway in no time. FYI this is so powerful you have to help pressure towards the surface or the disc will take off like a UFO.... starts with one pull, would recommend to anyone looking for power.

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.

I bought this to replace my old power washer of many years and I wish I would have traded up sooner. This unit starts perfectly and everything works perfectly. The only problem for me is that I am in my sixties and the unit is very powerful, to help with this I bought the extra handle grip to use and being able to use two hands makes it a lot better.

I live in the US Virgin Islands had this shipped. Lots of cleaning after 2 cat 5 hurricanes. Only used a couple of times and so far does a good job. Cleans concrete well and adjustable pressure on the pump also allows you us use it on lighter things like screens. This is not being used for commercial purposes so I hope it lasts.

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 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)!!!
