I was actually shopping for one of these last year & put it off. Was looking for at least a 15" model, but the 14" is not much of a difference. Having 4 wheels for stability was a must. Now we can finally clean the so called patio (slab of concrete) in the yard easier than using just the wand on the pressure washer. That takes a long time if your doing alot of ground. I speak from experience.
Thank you Woot!
So I have ryobi surface cleaner that works great. The rotating arm has a jet at each end which is fixed at some angle. This one is intriguing in that you can adjust the dispersion of the cleaner heads but it only comes with three nozzles. It really should have six. Perhaps the manufacturer is assuming you already have the matching/corresponding nozzles that came with your pressure washer. 
I hadn’t seen anything like this before and I am thinking about it for my deck
I learned about them from YouTube videos of those landscapers who do people’s yards & landscaping for free. They do it for their viewers & ad revenue of course, but its still a win win for everybody. These things work great. Go on amazon & do a search, they are not cheap. The plastic ones without wheels don’t count they look useless. I’ve done my neighbor’s alley by hand with the wand & that took forever.
You realize the unit has fixed nozzles just comes with spares you use on the end of regular wand?
Just received one of these, on this sale. The page on Woot that has a photo of the underside of the housing, with descriptions of the three angle/jets, is misleading. The three colored/angled-dispersion jets are (apparently) to be used directly at the end of the two straight extensions, without the 14" floor cleaning unit. If you look at the very top photo, that shows all the pieces you get, it includes O-ring replacements for the adjustable neck, where the extender pipes hook-on, and right next to them, two 11mm-wrench, screw-in nozzles for the spinner pipe, and teflon tape for some of the screw joints (not sure which one, or if all of them. Thos ar the only nozzles for floor cleaning. (A guess), That they included the three colored nozzles, because those extender pipes and quick-connect nozzles, come in different diameters, and you might want to use them as extensions to your normal spray gun. I call this a guess, because the instructions do not mention those nozzles, and if the extenders fit on your spray gun, then so will the spray nozzles that came-with your spray gun and pressure washer. And if you need new nozzles, you’ll likely also need a different spray gun. Either way, the parts you want are extra screw-in nozzles for the rotating spray bar, and one set is pre-installed, an extra set in a little bag inside pachage. HTH..
This dropped-shipped from Amazon (TBAnnnn), and arrived halfway across the country in 2-days from order fulfillment. And FWIW, I have not yet tried this unit, though I have tried others, that did not do as good a job as I needed, and I expect to have that same experience with this unit and one of my electric pressure washers, because the limitation is water volume. I think it will work very well with a gas-powered 3-4 gpm washer. My reason for buying it is that trying to use a spray gun with extensions to blast dirt, mold etc from pavers is a very slow PITA. And if you don’t keep the spray nozzle a consistent distance from the surface, the final result looks multi-shaded, not professionally cleaned. With this unit, consistent distance is assured, so cleaning will be faster and less PITA. That means I can go out every few months and do a quick job, less dirt, even with electric. Fast & consistent is my need.
I received mine today… def one for doing something pretty much not dirty.. I tested it with 4 of my 6 pressure washers, the last 2 did not bother since they are 4000 PSI 5 gallons a min, and pretty sure that thing would explode. It would not even break the dirt on pavers, did not even touch moss imbedded. That was with first 2 electric, then 2 gas machines, 2500 PSI 1.4 gpm to 3000 psi 2.3 gpm. Then tested a cheap rotating nozzle vs that woot special, and it was done in 1/10 the time, and clean. So it , this thing appears to be a chinese copy of the 15" Karcher. all that said, I only bought it because it looked like it would be perfect for the paver walkways and the one I normally use is a little large for that. Hope others have better results with it, but even a Northern star wall washer is even better than this thing.. My go to cleaner is below:
Purchased one last week during the sale, and tried it on my lower powered 2200 psi weird brand electric pressure washer (who knows what the actual generated pressure is). Found that there wasn’t enough pressure to spin the rotating arm. Spinning the arm by hand, I could feel that it was binding at one spot in the rotation. Watched some YouTube videos on surface washer maintenance, and decided to take mine apart. It’s constructed similar to a Karcher unit and has a snap ring holding the arm and bearing(s) into the housing. I was pleased to see the high quality of the construction, and there are actually two bearings on which the arm spins, not just one that I saw in the videos. After pulling the arm and bearing assembly out of the housing, the arm spun free and easy on the bearings (good sign, not a bent shaft). Looking into the housing I could see where something had been rubbing on a flat surface above where the bearings sit. Looking at the top of the bearing assembly, I could see paint was worn off the ears of the upper snap ring (that hold the bearings onto the shaft). So the interior roof of the housing wasn’t entirely perpendicular to the rotating shaft, allowing the snap ring ears to touch the housing during part of the rotation, thus the binding I could feel. I removed that snap ring, and filed the ears a bit thinner, and reassembled the unit. Now the arm could rotate without binding. Connected to my pressure washer, and she spins!
Tried it on my driveway, and quickly found that because the side brushes ride so low to the surface, water remains trapped under the attachment, causing the spray heads to be ineffective trying to spray though deepening water. I’d like to raise the brushes a bit, but because of a lip on the housing, that becomes difficult. So instead, I’m going to add some washers where the wheels attach to the housing, to raise the whole housing (including the brushes) a bit off the ground, giving a space for the water to escape and not be trapped underneath, hindering the spray heads. Have to experiment to find the right amount.
Wow. Great job. You are a true wooter.
A person who’s not afraid to void their warranty.
I like the cut of your jib.
