I've owned the K-12 surface cleaner for 3 months and have used it several times and it performes as advertised! The cleaning effect is the same as using the regular nozzle except it covers a wider area ( 12 inches ) and no water splatters,just a small amount oozes from under the unit. It does "float" and makes cleaning floors,decks, and walkways a snap. I haven't used it on vertical surfaces but think it would work as well.

I was worried after reading other reviews, but it works well with my presure washer. Model K 3.87. Even got the bonus of having a extension that works with my sprayer and wash brush too. All the adjustments work well and I cleaned my driveway (1000 SQFT)and will do my deck and garage floor too. The "hovering system" with twin sprayers and brush around the edge cleans EVENLY and keeps user dry. I am not sure about vertical surfaces, although the unit is light. I would buy again, just make sure it fits your washer, with the "push and twist" Karcher connection system.

Based just on the first couple of hours of use I have the following comments. It believe it is doing a good job of cleaning my deck - probably no better than just using the fan pattern from the Karcher pressure washer, but much faster. However, the top knob which adjusts the "Spray Power" was stuck in one position on mine. I called Karcher and their rep said that is the way it is supposed to be (not true, according to instruction book). Finally after tugging and muscling it I finally got it to turn, as it should have done in the first place. Also, the other adjustment (Air Flow Control)does not catch onto the detent and just flaps around freely as it is being used, so is of no use at all. I was thinking of taping it into one position (hey, a use for some of that duct tape my wife recently bought!), but it should work properly in the first place.

I used the Karcher surface to clean off years of grime from our patio, porch, and sidewalk. The concrete looks so much cleaner and brighter. It enables one to cover a larger area in less time,than if you used just the wand spray. I am glad I purchased it.

The Karcher K-12 cleans my brick side walks and patios better than I hoped for.It even cleaned moss build up 4 to 5 times faster than using a power sprayer without the K-12. This attachment provides a powerful wide cleaning area and does not require alot of effort to use.

I bought this a while back to use with a Karcher HD 3500 DH pressure washer. When the time came to use it, I found that the Karcher K12 Surface Cleaner does not fit the trigger handle of my Karcher HD 3500 DH pressure washer. The fitting is some type of unusual connector that must be unique to other Karcher pressure washers.

This was a waste of good money. Amazon.com should warn that this surface cleaner does not fit all pressure washers ( even if they are Karcher pressure washers ).

I have the 1600 system; I checked Karcher's website before ordering this to be sure it would fit on my system. It does a fantastic job on my concrete driveway and patio surfaces, uses much less water than the wand, and the "floating" makes it very easy to use. I have tried it on vertical walls, (per the manufacturer's literature it can be used that way) but it's much trickier because it's harder to keep it under control. But for horizontal surfaces, I think it's a winner.

I take back all that I said. It does fit the K2-45 and it works extremely well. I just haven't figured out the technique for vertical surfaces. This is a very satisfied customer. I needed to re rate it to a 4.

We purchased the K12 along with the K520M pressure washer, it saved much time cleaning a filty pool cement deck, we had to rinse off and do detail cleaning with the Quatro nozzle. We are totally satisfied with this attachment, and very pleased with the results.

This attachment does not fit my Karcher K 2400 HH Gasoline Engine Pressure Washer. The factory rep advised that this attachment is ONLY for Electric Powered Washers at 2300 psi and below. You CAN NOT get an adaptor to use it with Gasoline Powered Washers. I wish Amazon would report that in the description. It sounds like a good attachment if you can use it.
