Works great!

Will not last!!!!  I have average 2 car garage driveway and small amount of sidewalk and small back patio. Cleaned it all exactly once. Came back this year and the bushings are work to the point it wwont spin fast enough to clean. Checked/cleaned tips to no avail. Avoid this piece of equipment.

It stopped spinning after 3 uses. It's not clogged, but it's leaking through the "T" connection. Has 2 plastic washers/bushings that are not available from Simpson's!! Now have a piece of junk! Called Simpson's customer service and they just don't care to provide any service.

I got this a couple of days ago and used it yesterday. It took an otherwise long tedious job and cut the time and effort by 2/3. It took a couple of trigger pulls to get the nozzles rotating but once they started there was no problem. The cement work around my house was pretty dirty and this attachment made cleaning a lot easier.

I bought this surface cleaner at the same time as a gas powered Simpson pressure washer. It doesnt work Not on the Simpson or my small 2400 psi electric power washer.  The nozzles will not spin under pressure. Turn the pressure off, they spin freely by hand. Pressure on, they dont move at all. It is obvious the water pressure is pushing on the hub/bushing and they keeps the nozzles from spinning. I've lubricated it. No joy.

Works terrific! Exactly what you need if you've got a lot of concrete to clean.

Real handy add on for your washer

It worked in a marvelous way! Easy to use and it did the job well! Everyone was soooo impressed with the job completed.

Cleaned our concrete patio and wood deck floor with this attachment. Very easy to use and it did an amazing job. Everything looks new again!

The arms with nozzles don't rotate properly. You have to pull the gun trigger tap tap more than a few times to start the proper rotation.
