Finally clean driveway and side walks

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.

True pro Power Washer at home owner pricing

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.

Very Powerful Pressure Washer

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.

Great Pressure Washer

Very happy i paid a little extra and got the Honda engine. It performed fantastic, no more than 2 pulls to start the engine each time. Unit had plenty of power to soft wash my two story house. I already upgraded with an additional 100 ft of simpson monster hose so i can leave my unit stationary and clean the entire house.

GREAT PRESSURE WASHER!!!

I ordered this for general use around my home including cleaning siding, concrete, my tractor and its equipment, plus getting river mold off of my boat. It does a great job. It was very easy to assemble and I had it ready in just a few minutes. Make no mistake. This washer is a brute!

Absolute beast

From the second I unboxed this machine I knew it was going to be phenomenal. It’s a beautiful piece of equipment and it performs just as beautifully. I purchased this for my power washing business and it constantly outperforms its price tag. Stop looking and just buy it already.

VERY POWERFUL

Was easy for me to pull and start.. I am 78 years old and previously owned Simpson 4000 psi/4gpm with a Honda engine. I had to purchase this one b/c the one with a Honda engine was more than I could afford. (Same pump as previous Simpson)
