Simpson 15 in. Surface Cleaner

Conceptually this product saves a lot of time. The bad thing is that time saved is a one time affair. These are single use surface cleaners that are unserviceable and sadly in two cases have failed their second attempt at use. One was RMAd. The same unit was used once and subsequently failed to spin on second use a year later. The price point seems to be aimed at the homeowner market so these are a once a year thing, at least for me. I’d stay away from this model and look elsewhere.

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.

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.

I bought this surface cleaner along with a Simpson pressure washer as a set. At first I was having the sma eissue as everyone else: it stops spinning. Well, I figured out the issue. It appears that the angle of the nozzles is not set properly in the factory. I got a socket and slid it over one nozzle, gave it a tiny bit of a twist away from perpendicular to the ground (see photo attached) then did the other nozzle, and presto…problem solved. I realize you shouldn’t turn it too far, because then it will not provide enough force to the surface you want to clean. But there is a sweet spot, a balance between cleaning force and rotation that can be had. It only took a couple of degrees of angle change, and now this thing works better than ever!

Stopped working after one year and 4-6 hours of use. Do not buy.

Used to do our driveway, and sidewalk. Used about 4-5 hrs. Worked great. Then quit spinning, attempted to live main bearing assembly. Worked briefly then immediately stopped. Do not buy.

I bought this to clean my driveway. If the spray arms do not spinning with enough speed, they ended up making terrible marks. Very disappointed.

This product was included with Simpson power washer that I bought about 1 month ago. It worked great on two driveways but now doesn't want to spin. When trigger first pulled, it spins normal for about 10 seconds then slows down to a stop. Suspect binding in shaft. Plastic parts? Love the concept but will buy competitors product as a replacement. Other reviews state no replacement parts..?

Arm quit spinning after about 6 hours of use. Going to take apart to see if anything can be done.

Worked for several applications then the arm stopped spinning. Same issue as many others. No blockages and did not find any replacement parts. Do not buy this product. Go with a different brand.

I was only able to use the Simpson surface cleaner for about 3 hours of total time before it quit working properly. Water comes out of the two nozzles, but the arm will not spin. The arm spins freely when I push it. This is a piece of junk.

After 30 minutes of use this stopped spinning. I looked at the reviews after my problem (mistake!) and Simpson suggests cleaning nozzles and Checking screens. I don’t understand why this needs so much maintenance - I’ve had a slightly cheaper unit that lasted 4 years with zero problems and zero maintenance. I’m returning this.

As all other's have said, complete junk after one use. Solid machine, especially with the Honda motor, but the surface cleaner clearly needs help. I hope they have pulled this design from the shelves.

Worst product I've seen in my entire life! Some worked for 30 minutes others 4 times and only one lasted 10 times or so. No replacement jets.

The first one of these that I purchased was replaced as a warranty claim, even though my product was just outside the normal warranty. While I appreciated the courtesy of a free replacement, the replacement didn't fare any better than the original. The replacement worked fine for two uses over about a two-month timeframe. When I tried using it a third time, the heads would no longer spin. Water would spray just fine, but the spinning action was non-existent, rendering this tool useless. This complaint is so common that Simpson really needs to fix this or stop selling these. I have two other surface cleaners (off-brands from Amazon) that have lasted for several years with no issues.

Wished I didn't throw out my old surface cleaner when I bought the new Simpson power washer that came with a surface cleaner. I had another manufacturer surface cleaner and cleaned great but this Simpson surface cleaner was not rotating quick enough to effectively clean and had to use the typical spray nozzles to finish the job.

The unit seemed be a quality unit. The problem was the bearing/bushing for the rotating spray wand seized 15 minutes into use. Used a 2200 PSI Power Washer so I know it wasn't spinning too fast to melt the components. No parts support from factory. Was considering a new Simpson Power washer but having second thoughts now.

Hello , i got this unit last week 09-29-23 and for the first couple of hours it worked great . then it started to spin slow . checked the nozzle and it was clear . i even cleared the center hub with Air . tried it again and it worked for a couple more hrs. . what kind of lube or grease to you recommend for the center hub . I think from all of the concrete debris it gets into the center hub and causes it to spin slow . or is this a poor design , i have a SIMPSON Cleaning MSH3125 MegaShot 3200 PSI Gas Pressure Washer, 2.5 GPM, Honda GC190 Engine

Would not buy, bought for one project and it was the only one in town that I could get day of. I saw the reviews and figured I would give it benefit of the doubt. Used to clean an area 120'x50' smooth warehouse concrete. Worked great for first hour and a half, then stopped spinning. Checked the spinner and hub had some play on the bushing. One of the spray tubes was loose and adjusted angle back. Horrible vibration issues after, the 4 small mounting screws that mount into plastic housing had to be tightened every 30 min they worked out multiple turns and were not stripped. The Bushing wore enough through vibration and wear that it was rubbing on the housing.

I purchased this a year ago and it worked great then. Tried it again and now it won't spin. If rotates freely and nozzles are good and positioned correctly, good pressure and water flow comes out but it won't spin.
