Simpson Cleaning 80165 Universal 15" Steel Pressure Washer Surface Cleaner for Cold Water Machines, 1/4" Quick Connection, Recommended Min 2200 PSI up to Max of 3700 PSI, Black

Fantastic product! Just used it for the first time and it works great. What a time saver and it was easy to connect. I did find that when it is first "turned on" that you need to wait a bit (few seconds) for the arms to move full speed; otherwise, you get a swirl pattern of cleaned area, rather than the whole area under the cleaner being cleaned.

This tool is amazing. Shocked at how easy and fast it was. I plowed over my pavers with gravel in between them could hear rocks banging around from time to time but never once has stopped working. Liked it so much I bough another just to display in my garage. For the price as long as it handles my entire house once I’ll buy it new every time. Normal job takes 6 hours. Done in two. Half the fuel.

Highly disappointed - even after purchasing this TWICE.Bought a Simpson pressure washer and other accessories which are FANTASTIC and can't say enough about how happy I am with them.But this accessory was a big let-down. I was honestly a little leery at the 4.1-star reviews, but I figured someone didn't know what they were doing or, as I often do, thought that somehow I would beat the odds and get a working, functioning unit deserving of the 5 stars others have left. When it arrived, there were multiple layers of packing tape all over the bent and worn box (which had been shipped inside an outer shipping box). When I opened the box, the plastic bag surrounding the cleaning head had been badly crumpled and torn, so it was obvious it had been returned - likely more than once. When I attached it to the pressure washer, only one of the two spray heads emitted any water and only a small trickle at that - no high pressure at all. Disappointed that this "new" sprayer didn't work right out of the box. The instructions directed me to clean the nozzles with the included cleaning tool which I did several times. After fiddling with it for over an hour, the best I got was one head to spray and the other was dry as a bone - nothing. So I returned it and reordered another. I waited to return the first until the replacement arrived so as not to get the same, defective one again.The second one arrived and again, the box had been re-taped - definitely a red flag! When I opened it, everything looked great, though the plastic bag it came in was crumpled and torn, but not to the extent the first one had been. When I hooked it up to my new Simpson pressure washer, the spray nozzles put out a ton of water under pressure, but the arm wouldn't rotate! I removed the head and rotated the arm by hand and it spun around just fine with virtually no effort. That's what you want, right? But when I put it back under pressure, the arm just sat there, the nozzles shooting pressurized water, but without any movement of the arm at all. When I tried to clean with it, I got narrow stripes instead of one big circular cleaned surface. Again, I fiddled with it for about an hour, but no matter what I tried, the arm just wouldn't spin on it's own. So now this second one is going back, too!I don't appear to be the only one with this issue if you read through other reviews. I'm really disappointed because I've been so impressed with the other Simpson products I've purchased! I won't try this a third time - instead I'll buy another (higher rated, less expensive) brand of the same thing. Sorry, Simpson. I gave you a second chance, but you failed twice on this one. But I HIGHLY recommend your pressure washer! Wow!UPDATE- A few months later, I noticed the Kärcher brand surface cleaner go on sale at a price I couldn't refuse. WOW! What a difference! Worked beautifully out of the box and several times since. If you're in the market, definitely get a Simpson power washer (with a Honda engine), but get the Kärcher surface cleaner for it. It's plug and play with Simpson power washers (no adapters needed). Outstanding performance and no regrets.

A couple years ago I bought the Karcher surface cleaner and ended up returning it after the first use. If you tried to push it forward the front of it would dip down and drag on the concrete making it almost impossible to do. I would have to simultaneously lift up on the wand while pushing the cleaner forward which was extremely difficult to do. I thought maybe the angle was too direct so I added a wand extension but that didn't help. I would have to lift and push at the same time which made for crappy cleaning and it was difficut to do. The only real cleaning it did is when I drew it back toward me and even then the results were below average. The Karcher left circles of unclean concrete which you could only correct by unhooking the cleaner and using the spray attachments which defeated the whole purpose of having the surface cleaner in the first place. After I returned it I just figured they were all like that so I have just been using the spray attachments since then, which uses a ton of water plus takes a lot of time. I haven't used the pressure sprayer as often as I should because it took so long to clean. I have a huge back patio around my pool, driveway for a 3 car garage, and my house is on a corner so there is a double crapload of concrete here to clean. A couple days ago I was back at it with the pressure sprayer and I decided it was time to give a surface cleaner another go. I have a 3200 psi Simpson which is what the Karcher surface cleaner was rated for, but this time I decided to give the 3700 psi Simpson pressure cleaner a go. What a difference. This thing is the real deal. You can actually push it forward and it skims across the surface like it's supposed to do. It cleans without leaving the circular streaks. It does exactly what it's supposed to do and it makes cleaning a breeze. Today in 3 hours I did pretty much the same surface area as I had done the previous 2 days combined using a fraction of the water I had used. What used to take me a week will now take a couple days. If you are looking for a surface cleaner for your gas powered pressure sprayer this is the one.
