I bought this a few weeks ago and my husband has already used it on our: metal security patio door; House; concrete patio, porch steps, and sidewalks; and brick patio. Everything looks so clean! This is a great item to have to use for all outside cleaning jobs.

I bought this to use around my house for house washing, patio cleaning, siding and driveway cleaning. Does an awesome job. The only negative I noticed was on the concrete driveway the whole unit would spin in a circle from vibration. Had to set it in the grass to stop from rotating.

I’ve had my Simpson pressure washer a few weeks now and I have to say, it’s one great machine. I’ve used it on my house and driveway and then took care of the three elderly ladies drives that live by me. The pressure washer has great output and is much easier to move around my yard than some of the other machines I’ve had in the past. Honda motors are a great choice as they are easy to work on when needed and the Simpson pump has always been one of the best. Look forward to Father’s Day weekend to put it back to work on the outside of my shop.

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.

Great pressure washer with a Honda engine and a AAA pump. Much better than a Ryobi or similar that is either made in China or has parts that are made in China. This thing is a BEAST ! It will clean anything that an average homeowner will need. It is much quieter than the Ryobi that I previously owned. I received very good support from Simpson before and after my purhase. I chose Simpson because I wanted something that wouldn't quit on me after a few years of homeowner use. Simpson's reputation for quality and support is the reason I chose to purchase this item.

The unit has great power. The specs indicate the unit has pneumatic tires. It has solid tires which adds to its inability to absorb its own vibrations and “walks” across pavement. I plan to take this up with Simpson and HD. Vibration isolation pads or mounts should be incorporated into this design.

I bought this to pressure wash my house and driveway. Using only the green tip it works great. The best thing about all this power is time. My son in law has an 1800 psi electric pressure washer and if I would have used it on my project I'm guessing 12 hours. With the 4400 psi I did the entire project in 4 hours.

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.

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 have used this pressure washer only a couple of times and both times it exceeded my expectations in cleaning both with my disc and the15 degree tip. It's performance equates to (5 stars) however I deducted one star for difficulty in relocating the unit. The handle is too low and too short. When pulling the unit it would hit my feet and trying to push it I am bent over in an uncomfortable position. I would prefer it being equipped with a fold-down handle that I could lift up to relocate it. I am an older guy and this may be of no concern to younger operators, but a big issue with me.
