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.

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.

After 5 hours of use so far so good. Very powerful when paired with a correct size wheel

Great pressure, starts easily, works great. Highly recommend it

When you put together the handles they kind of loose ,

Very clean. Easy to use. Good purchase. Lots of accessories. Powerful.

Happy we bought it works great easy setup powerful easy to use for my wife too. Price was great

I took this thing off the truck and right to work. Great Product.

I just assembled not used yet but looks like it is very robust

Just purchased great power and water pressure. Great home cleaning machine!
