KärcherPressure Washer Surface Cleaner 15", Quick Connect, 2600-3200 PSI, Ideal for Driveways, Patios, Decks, Sidewalks

This power washer attachment worked beautifully! I used it for 40 min. or so on our composite deck which was heavily stained by leaves, etc. It was easy to maneuver (I'm a older woman of average strength) and took the grime and stains right off with just one pass for the most part. I went over extra-dirty areas twice. We had not power washed our deck in years and had just used a spray-on, leave-on cleaner which did an OK job. Now our "beach-gray" composite deck looks as bright as new. The attachment made the job take half the time of just the regular sprayer wand. It wouldn't fit under the railing, so I'll use the wand only to clean that perimeter area. Now we're thinking of several other outside areas (and the garage floor perhaps) where we can use this. Seems well constructed, so hopefully we can use it for years to come.

The only reason I give this tool five stars is because a six-star rating isn't available.After replacing a decrepit deck with a beautiful, new two-level deck built with composite materials instead of traditional lumber, I vowed to keep it looking as close to new as I could. The first year, I used a long-handled stiff brush, some Simple Green, a garden hose and a whole lotta old-fashioned elbow grease, once a month. After the first time, I dreaded having to face this chore every four weeks. Toward the end, I simply couldn't get myself worked up to do it. The second year, I bought a pressure washer - but still had a fair amount of regular elbow-grease-and-stiff-brush action. This year, I added this surface cleaner to the deck-cleaning arsenal.Holy Smokes!! What a difference this tool makes!I can now clean the deck in less than 1/2 the time it took when using the brush & pressure washer - and maybe 1/4 or less, the time it took with brush, bucket & hose! In addition to cutting the time to a fraction, it's also made the job tremendously easier - no more effort than running a vacuum cleaner over carpet! The tool simply glides over the surface, and the powerful spray from the dual jets blasts even ground-in dirt free of the 'wood grain' of the composite material. The brush skirt of the tool keeps the water from going everywhere and keeps the mess to a minimum. The wand extension rotates from vertical to horizontal and actually lies flat, so I can maneuver the tool under patio furniture and into spaces that don't have vertical clearance. The materials seem quite substantial and the workmanship is top-notch. This is absolutely a high-quality product leaning more toward "pro" than "consumer" on the "prosumer spectrum"Our deck came out so clean, it quite literally looks like it did on the day it was built! This surface cleaner actually turned a tedious chore into a pleasant task - the only thing I "regret" is that I don't have more uses for it!If I had known how much simpler and more effective this would be, I would've purchased the pressure washer and this surface cleaning tool when the old deck was torn off, and had it ready to go when the new deck was complete. This has been the smartest tool purchase I've made in quite a long time. I guarantee you won't regret it, either.

I included several photos of potential interest. The surface cleaner performed well, allowing me to clean about 1,000 square feet of concrete driveway, patio, and sidewalk with no real problem. The infamous large top and bottom nuts that so many reviewers have referred to did finally start to loosen after I had cleaned about 700 square feet. I kept checking the top and bottom nut thinking they would loosen, but they didn't until I was about 80% done with the job, then the one underneath started to loosen. This is a problem if you don't have anything big enough to tighten them. I don't really have anything proper, but I was able to get it tight using a VERY large channel lock (model "460" -- see photo) which is a fairly huge tool that I expect not that many people have on hand. A smaller channel lock tool, the one I'm betting lots of people do have (model 420), was not big enough to tighten it without a lot of marring of the plastic (nylon?) nut. So beware of that if you don't have something to tighten the nuts, or if you aren't brave enough to do some drilling and connect the top and bottom nut with a wire or bolt (etc) like some other reviewers have done. I'll probably do that eventually, but wasn't about to until I could ensure that the unit worked ok. I don't imagine Amazon would react well to giving a refund if you have modified the unit.As far as the operation of the unit, it was quite straightforward and cleaned the surface very well. You can see from some of the photos the before and after conditions. It does give a vigorous cleaning and did remove some of the top layer of the concrete, so, if you're squeamish about that, then you'd probably be better off to just leave your concrete a little dirty. I will not clean mine again for a few years for that reason. I also cleaned a set of brick steps which were very dirty and it did a good job on them, but I spent as little time as possible moving over them to avoid excessively damaging the mortar. I included a photo of the pressure washer I used since I figure a lot of people interested in this Karcher cleaner might have a similar washer. It did just fine with the surface cleaner, and connecting the wand to the cleaner was very easy. Also, an opinion on getting some type of extender for the wand -- I am not a super tall guy, getting up there in age a bit, and I did have to spend a couple hours bent over a little while using the regular spray wand that came with my pressure washer. It didn't bother me a lot, but if you are super tall or susceptible to a lot of back issues you might want to consider that. I didn't want to spend the extra money on an extender, but if someone had walked up to me and offered me one while I was doing the work I wouldn't have turned them down.This cleaner did save a good bit of time compared to spraying the surface with just the regular cleaning nozzles, and it did a much more consistent job. It took a few swipes to get the hang of how much overlap and how long to hover over the surface. Be sure and read the manual which tells you not to stay over the surface more than 2 seconds, but I found that to be a little too long, so I counted as I pulled the cleaner down the driveway, trying for about one second over any given spot. I overlapped about 1/4 to 1/2 on each pass and it seemed to work well, but again, this thing is fairly aggressive with a 3,000 psi washer, so be careful not to damage your concrete. Also, I found it to be a lot less awkward to pull it along instead of push it.I do recommend the surface cleaner, and, except for the loosening nuts issue, I would give it a 5 star -- it is offered at a good price and performs its job. So, if you're a homeowner (etc) and will only be using this for typical homeowner use every couple of years this thing is probably a good purchase. Since I've only had it a couple of weeks, and I've already cleaned everything I intended to clean with it, I can't say anything about its long-term durability.

The Kärcher Turbo Nozzle is a fantastic addition to any gas-powered pressure washer setup. Designed for up to 4000 PSI, it delivers a powerful, rotating spray that makes cleaning tough surfaces like concrete, brick, and decking incredibly efficient.The quick-connect design makes it easy to attach and detach, saving time during setup. It’s durable and built to withstand high pressure, providing consistent performance even with heavy-duty use.If you’re looking for a reliable nozzle to tackle stubborn dirt and grime, this is a great choice. Highly recommended for anyone who wants to get the most out of their pressure washer!
